Question

A small lizard spends the morning hours lying in the sunlight until its body temperature rises. Later on in the day, the lizard rests in a shady area until its body temperature cools. This type of behavior is important to

1. maintain homeostasis
2. detect variations
3. attract mates
4. obtain nutrients

Answer 1

1. Maintain homeostasis.

Since lizards are cold blooded animals, their body temperature depends on environmental conditions. As a result, they modify their behaviour to maintain homeostasis.
