Question

Why do animals need more energy as compared to plants?

Answer 1

Animals require more energy than plants.
This is due to various reasons. Some are :
1) Animals are motile organisms whereas plants are non-motile. Being motile requires more energy.
2) Plants have many dead tissues whereas this is not in the case of animals. Hence, again animals need more energy.

Answer 2

•Plants do not show locomotion because they are rooted in soil at a fixed place..

•They don't need efficient energy supply for regulating their body temperature to that of animals who are generally warm blooded..
