Why do animals need food in their bodies?

Why are animals important to the developing world?
Thus, moderate consumption of animal-sourced foods plays an important role in achieving a nutritionally balanced diet, especially in the developing world ( 11 – 13 ).

Why do all the organisms need to take food?
Organisms need to take food so that energy can be released after oxidization of the food (respiration). The nutrients from the food after respiration gives us sufficient energy to do work. The two main modes of nutrition are: Autotrophic Nutrition- mainly in plants.In this mode,organisms prepare their own food.
Why do all living things need food?
All living things need food (for energy) to grow and reproduce. Some organisms (such as plants) make their own food from air, water, and sunlight. Other organisms must eat plants or other living things to get their energy. Animals require different amounts of space to find food, water, shelter and a mate.
Why Cant animals make their own food?
