1. The functions of food are as follows:
• Food supplies the body with energy. Energy is used by the body for doing various activities
such as walking, running, writing and talking. The heart needs energy to beat all the time.
• Food enables the growth and development of the body. A tiny organism grows on to become
an adult because of the intake of nutritious food.
• Food helps the body to produce new cells that are required to replace old, worn-out cells. The
process of building new cells happens round-the-clock in our body.
• Food protects our body against germs and diseases. It gives our body the ability to fight
infections.
• Food also has a social function; all festivities happen around food.
2. Following are the parts of plants eaten by us: Roots The roots of many plants such as carrot,
radish, turnip and beetroot serve as food for us. Stems Sugar cane, potato, ginger and onions are
the stems of plants that we eat. Leaves that we eat include cabbage, spinach, lettuce, coriander,
mint, amaranthus and fenugreek. Flowers We eat cauliflower, broccoli and banana plants. Fruits
Apple, mango, brinjal are some of the fruits we eat. Some pulses and cereals are seeds of plants.
3. Meat is obtained from animals such as goats, sheep, chicken, duck, fish and prawns. Meat is a
good source of proteins. For example, roasted chicken and grilled fish Milk and milk products.
Animals such as cows, buffalo, goats, sheep and camels give us milk. Milk is a rich source of protein
and calcium. Calcium is essential for the healthy development of teeth and bones. Various
products, called dairy products, are made from milk. These include curd, paneer (cottage cheese),
cheese, butter, ghee and cream. Eggs We get eggs from hen, duck and goose. Honey Honey is a
sweet liquid made by bees from the nectar of flowers. It is gathered from beehives. Honey has
many health benefits.
4. Some carnivores and omnivores, known as scavengers, are animals that do not hunt other
animals but feed on the flesh of dead animals. They are extremely important for the environment
as they help to keep it clean by eating up the dead bodies of various animals. Vulture, crow, jackal
and hyena are well-known scavengers. Decomposers are organisms that break down dead and
decaying organisms. When a plant or an animal dies, its decaying body is broken down or
decomposed by the decomposers. The nutrients present in the dead body are returned to the soil
by the action of decomposers. Bacteria and fungi are the most important decomposers.
5. A food chain is a sequence which shows how living things in an environment are related to each
other according to their feeding habits. All food chains begin with plants, as plants make their own
food by photosynthesis. Animals eat either plants or other animals. The arrows in a food chain
show its direction. All animals depend upon plants either directly or indirectly. Example: Plants >
grasshopper > frog > snake > eagle
