Answer:

Nutrition in animals

Nutrition is the process of obtaining food and then using it for obtaining energy, growth and repair of the body. There are five main processes concerned with the use of food by animals. As we know that Plants produces their own food by the help of photosynthesis. But animals are heterotrophs and hence they depend on other organisms for their food. This readymade food comes either from plants or from other animals. We are also animals and obtain food from plants in the form of rice, pulses, vegetables etc. and foods like milk; eggs, chicken, fish etc are obtained from other animals.
