True. Animals are indeed the greatest gift of nature because they provide us with numerous essential resources and services. Animals supply us with food such as meat, milk, and eggs, which are rich sources of protein and nutrients necessary for human survival and health. They also provide us with valuable materials like wool, silk, leather, and fur that are used to make clothing and other products. Additionally, animals play crucial roles in maintaining ecological balance by pollinating plants, controlling pest populations, and contributing to nutrient cycling in ecosystems. Many animals also serve as companions and provide emotional support to humans. Furthermore, animals have been instrumental in advancing human knowledge through scientific research and medical discoveries.
True. Horse hair is used as bristles in small painting brushes. The hair from horses is particularly suitable for this purpose because it has the right texture, flexibility, and durability required for fine painting work. Horse hair bristles can hold paint effectively and allow artists to create precise strokes and detailed artwork. This natural material has been traditionally used in brush-making for centuries and remains a preferred choice for high-quality painting brushes used in both professional and artistic applications.
False. Wool is not the fibre derived from the silk worm. Silk is the fibre derived from the silk worm. Wool is actually obtained from the fleece of sheep and goats through a process called shearing. Silk, on the other hand, is produced by silk worms, which are the larvae of the silk moth. The silk worm secretes a continuous filament of protein called sericin, which hardens into silk fibre. This silk fibre is obtained by unwinding the cocoon that the silk worm spins around itself. Therefore, the correct statement is that silk is the fibre derived from the silk worm, not wool.
False. Ahimsa silk is otherwise known as peace silk, not mulberry silk. Ahimsa silk or peace silk is produced using methods that do not harm the silk worms during the extraction process. In traditional silk production, the pupae inside the cocoon are killed by exposing them to heat before the silk is harvested. However, in Ahimsa silk production, the silk worms are allowed to emerge naturally from the cocoon before the cocoon is processed, ensuring that no harm comes to the insects. Mulberry silk, on the other hand, refers to silk produced from silk worms that feed exclusively on mulberry leaves, which is the most common and highest quality type of silk produced commercially.
True. Penicillin is the best medicine for curing Anthrax. Anthrax is a serious infectious disease caused by the bacterium Bacillus anthracis. Penicillin is an antibiotic that effectively kills this bacterium and is considered the primary treatment for anthrax infection. When administered promptly after exposure or infection, penicillin can prevent the disease from progressing and can cure infected individuals. This antibiotic works by disrupting the bacterial cell wall, leading to the death of the pathogenic bacteria. Early treatment with penicillin is crucial for successful recovery from anthrax.
The correct matching is as follows: Cocoons are produced by Silk worm. Peace silk is otherwise known as Ahimsa silk, which is produced in Andhra Pradesh. Broilers are a type of Poultry raised for meat production. Sweet Liquid refers to Honey, which is produced by honeybees. Goat provides Meat as a food product. These matchings represent important animal-derived products and the animals or regions associated with them in daily life and agriculture.

Two important dairy products are paneer and cheese. Paneer is a fresh cheese made by curdling milk with an acid and is widely consumed in Indian cuisine. Cheese is another dairy product made through a fermentation process where milk is curdled and the whey is separated from the curds. Both paneer and cheese are highly nutritious foods that contain significant amounts of protein and calcium, which are essential for building and maintaining strong bones and teeth. These dairy products are made directly from milk and are important sources of nutrition in the daily diet.
The two types of fibres obtained from animals are wool and silk. Wool is obtained from the fleece of sheep and goats through a process called shearing. The fleece is then cleaned, carded, and spun into yarn that can be used to make clothing and other textile products. Silk fibre is obtained from the cocoon of the silk worm, which is the larva of the silk moth. The silk worm secretes a continuous filament that hardens into silk, and this fibre is extracted by unwinding the cocoon. Both wool and silk are natural animal fibres that have been used for centuries to produce high-quality textiles and garments.
The symptoms of Anthrax include fever, cough, and shortness of breath, which are similar to those of typical pneumonia. Infected individuals may also experience other symptoms such as nausea, vomiting, and diarrhoea. In some cases, anthrax can cause skin lesions or sores if the infection enters through the skin. The severity of symptoms depends on the route of infection and how quickly treatment is initiated. If left untreated, anthrax can progress to more serious complications and become life-threatening. Therefore, recognizing these symptoms early and seeking medical treatment promptly is essential for recovery.
Sericulture, also known as silk farming, is the cultivation and rearing of silk worms to produce silk fibre. It is an agricultural practice that involves breeding silk worms, typically the Bombyx mori species, and providing them with appropriate food, usually mulberry leaves, and suitable environmental conditions. The silk worms feed on these leaves and eventually spin cocoons around themselves using a continuous filament of protein. These cocoons are then processed to extract the silk fibre, which is used to make silk cloth and other textile products. Sericulture is an important agricultural industry in many countries, particularly in Asia, and provides employment and income to millions of people involved in various stages of silk production.
We should treat animals with love, care, and respect. Animals deserve protection and safeguarding from harm and cruelty. We must ensure that animals have access to adequate food, clean water, and shelter. It is important to avoid causing unnecessary pain or suffering to animals and to treat them humanely in all circumstances. We should recognize that animals have their own intrinsic value and play important roles in nature and in our lives. Treating animals well reflects our compassion and responsibility towards all living creatures. We should also educate others about the importance of animal welfare and encourage practices that promote the well-being of animals in our communities and in the wider world.
Kusuma Rajaiah, a Government officer from Andhra Pradesh, proposed the Ahimsa method of silk production. This innovative approach aims to produce silk without killing the silkworms. In traditional silk manufacturing, cocoons are boiled to extract the silk threads, which results in the death of the pupae inside. Ahimsa silk, also known as Peace silk, uses a humane alternative where silkworms are allowed to hatch naturally from their cocoons, and only the vacant cocoons are then used for silk production. This method has gained support from people concerned with animal welfare while still allowing for the production of high-quality silk fabric.
Wool possesses several important characteristics that make it a valuable textile fiber. It is resistant to heat, water, wear and tear, which means it can withstand harsh conditions and frequent use without deteriorating quickly. Wool has excellent moisture-absorbing properties, allowing it to absorb perspiration while keeping the wearer comfortable. It is an outstanding insulator against cold, trapping warm air within its fibers to provide warmth during colder months. Additionally, wool does not wrinkle easily, maintaining its appearance and shape even after extended wear, which reduces the need for frequent ironing and makes wool garments practical for everyday use.
Silk has numerous important uses across different sectors. First, it is extensively used in the manufacture of clothing due to its natural beauty, elegance, and luxurious appearance. Silk provides comfort in warm weather by allowing air circulation and moisture evaporation, while also providing warmth during colder months, making it suitable for year-round wear. It is particularly valued in the production of classical and high fashion garments, including traditional silk sarees and modern elegant dresses that showcase its lustrous quality. Second, silk is widely used in household applications for creating decorative and functional items such as wall hangings, curtains, rugs, and carpets that add aesthetic appeal to interior spaces. Third, silk has important medical applications in the healthcare industry, where it is used in the manufacture of surgical threads and sutures for medical procedures. These diverse uses demonstrate silk's versatility as a premium natural fiber.
Poultry birds are susceptible to several common diseases. Salmonellosis, which causes diarrhea, is caused by bacteria. Ranikhet disease, also known as Fowl pox, is caused by a virus. Aspergillosis is caused by a fungus. These diseases can significantly affect the health and productivity of poultry flocks and require proper management and preventive measures to control their spread.
Ahimsa silk, also known as Peace silk, is a humane method of silk production that was proposed in 1992 by Kusuma Rajaiah, a Government officer from Andhra Pradesh state of India. This innovative approach was developed as an ethical alternative to traditional silk manufacturing methods. In conventional silk production, cocoons containing silkworm pupae are boiled to extract the silk threads, which results in the death of the worms inside. Ahimsa silk eliminates this harmful practice by allowing the silkworms to complete their natural life cycle and hatch from their cocoons. After the worms have emerged and vacated the cocoons naturally, these empty cocoons are then collected and used for silk production. This method maintains the quality of the silk while ensuring that no silkworms are killed in the process. Ahimsa silk has gained considerable support from individuals and organizations interested in animal welfare, as it demonstrates that high-quality silk can be produced without causing harm to living creatures.
Workers in the silk industry face several significant health hazards due to the nature of their work. One major occupational hazard is arthritis, which develops because workers must stand for extended periods while reeling silk into yarn, putting continuous strain on their joints and lower body. Back pain is another common problem resulting from prolonged standing and repetitive motions involved in the silk production process. Vision problems also affect silk workers due to the detailed and close-up nature of the work, which requires intense focus on fine threads for long hours. Skin injuries can occur from handling rough materials and equipment used in silk processing. Additionally, workers in poorly ventilated silk production facilities are at risk of developing respiratory problems such as asthma and bronchitis. These health issues highlight the need for better working conditions, proper ventilation systems, ergonomic practices, and safety measures in the silk industry to protect worker health and well-being.
The processing of wool involves five major steps.
They are as follows Shearing, Grading (or) Sorting, Washing (or) Scouting, Carding and Spinning.
Shearing:- The fleece of the sheep is removed from its body. This is called shearing.
Grading (or) Sort:- The fleece from the same sheep may be different from different
parts of the body. It is sorted out into separate piles of similar nature. This is known as Grading (or) Sorting.
Washing (or) Scouts: The sheared skin is washed thoroughly with soap (or)
detergents to remove dirt, dust and grease.
Carding:- The dried wool is carefully removed. These fibres then passed through the rollers which are covered with fine sheet of thin wire teeth. This process arranges the wool into a flat sheet called a web.
Spinning:- The web is drawn into narrow strand and then passed through spinning machines. The spinning machines twist the strands into yarn. The yarn is wound to form balls of wool. This yarn is either weaved into fabric (or) retained for knitting.
Wool is a multifunctional fiber with a range of diameters that makes it suitable for various applications across clothing, household, and technical textile industries. Approximately two-thirds of wool production is used in the manufacture of garments, including sweaters, dresses, coats, and active sportswear, where its insulating and moisture-wicking properties are highly valued. Wool is frequently blended with other natural fibers such as cotton or silk, or with synthetic fibers, to enhance specific properties and performance characteristics. When blended with other fibers, wool adds drape and crease resistance to fabrics, improving their appearance and durability. Wool is also used in the production of blankets that provide warmth and comfort. Additionally, wool is utilized in manufacturing carpets that offer anti-static properties and noise-absorbing capabilities, making it ideal for both residential and commercial spaces. These diverse uses demonstrate wool's importance as a versatile and practical natural fiber in modern textile production.
Silk fiber is an excellent choice for manufacturing parachutes due to its exceptional physical and chemical properties. Silk is the strongest natural fiber available, providing the tensile strength necessary to support the weight of a person during descent. Despite its strength, silk is thin and light in weight, which is crucial for parachute design as it reduces the overall weight while maintaining structural integrity. Silk is easily packable and can be folded and unfolded repeatedly without losing its strength or developing permanent creases, making it practical for emergency equipment that must be deployed reliably. The fiber is fire resistant, an important safety feature for parachutes that may encounter friction or heat during deployment and descent. Silk dries quickly after exposure to moisture, preventing water absorption that could add weight or cause deterioration. Additionally, silk is resistant to abrasion and chemicals, ensuring that the parachute material remains durable and functional even when exposed to harsh environmental conditions or handling. These combined properties make silk an ideal material for parachute manufacturing where reliability and safety are paramount.
Honey is recommended for consumption by people of all ages due to its numerous health benefits and nutritional properties. Honey contains high levels of natural sugars, which provide quick energy and make it an excellent natural sweetener. It possesses strong antiseptic and antibacterial properties that help fight infections and promote healing. Regular consumption of honey has been associated with the prevention of serious health conditions including cancer and heart diseases. Honey can reduce the occurrence and severity of ulcers and help alleviate various digestive problems by soothing the digestive tract and promoting healthy digestion. It is particularly effective in soothing coughs and sore throats, providing relief from respiratory discomfort and irritation. These therapeutic and nutritional properties make honey a valuable natural product that supports overall health and well-being, which is why it is widely recommended for people across different age groups.
