Nutrition in Plants
All organisms require energy in order to stay alive. Energy is utilised to do the various bodily functions such as breathing, ingesting and digesting food, excreting, reproducing, locomotion, etc. Energy is obtained from food. Thus the process of intake of food is vital for the survival of an organism as it provides energy. This intake of food is called nutrition.
Nutrition in Animals
In order to survive, all living organisms require food. Animals cannot synthesize their own food. They have to depend on ready made food. They obtain food either directly from plants (by eating them) or indirectly (by eating other herbivores). The nutrition can be defined as the process which involves the utilisation of food by an animal to obtain energy for growth and development.
