Animals require more energy than plants.
This is due to various reasons.

Some are :
1) Animals are motile organisms, i.e.  they move around, which burns energy whereas plants are non-motile, pretty stationary and make their own food. 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.



  • It always depends what animal you are comparing to what plant
  •  what your definition of food is.
  • A large tree would surely suck up more nutrients from the ground than a tiny insect.
  •  probably it could be that plants need less food because they can produce their own sugars through photosynthesis.
  • whereas  food is the animal’s only source of energy.
