Question

Birds should feed more often than lizards. Give reasons.

Answer 1

Birds should feed more often than lizards because

1. Birds are warm-blooded animals and are more active.
2. Some of them often fly continuously for hours. So their energy requirement is more.
3. On the other hand, lizards are cold-blooded, sluggish animals and often go for hibernation.
4. So, their energy demand is relatively less.
5. Energy is produced by the oxidation of food materials.
6. So, to fulfil the higher energy demand, birds should feed more often than lizards.
