Explanation:

Question 6:

The two major sources of food are plants and animals.

• Plant sources: Plants like grains (wheat, rice), fruits, vegetables, legumes provide carbohydrates, vitamins, minerals, and fiber. For example, rice is a staple food in many regions, providing energy in the form of carbohydrates.
• Animal sources: Animals such as cows, chickens, fish provide proteins, fats, vitamins (like B12). For instance, chicken is a common source of lean protein, and fish provides omega - 3 fatty acids along with protein.

• What is fiber? Dietary fiber is a type of carbohydrate that the body can't digest. It is important for digestive health.
• Agricultural sources of fiber:
• Cereal grains: For example, oats have a high fiber content. The bran part of grains is rich in fiber.
• Legumes: Beans (like kidney beans, lentils) are good sources of fiber.
• Vegetables: Vegetables like broccoli, spinach, and carrots contain fiber.
• Fruits: Fruits with edible skins or seeds like apples (with skin), pears, and berries are rich in fiber.

• What is forestry? Forestry is the science and practice of managing forests, including planting, caring for, and harvesting trees for various purposes like timber, non - timber forest products, and environmental conservation.
• How does it relate to meeting human needs?
• Timber: Forests provide wood for construction, furniture, paper production. For example, pine wood is used in building houses.
• Non - timber products: Forests give us products like fruits (e.g., wild berries), nuts, medicinal plants.
• Environmental: Forests help in regulating the climate (absorbing carbon dioxide), providing clean air, protecting soil from erosion, and serving as habitats for wildlife which is important for ecological balance and also for activities like ecotourism.

Answer:

The two major sources of food are:

• Plant sources: Plants (e.g., grains, fruits, vegetables, legumes) provide nutrients like carbohydrates, vitamins, minerals, and fiber.
• Animal sources: Animals (e.g., cows, chickens, fish) provide nutrients like proteins, fats, and certain vitamins.
