Question

When a pelican gets hot, it opens its bill and flutters the sides of its pouch. This causes water to evaporate, which cools the pelican. What type of adaptation is the movement of the pelican’s pouch?

behavioral adaptation

life-cycle adaptation

physical adaptation

reproductive adaptation

Answer 1

Behavioral adaptation

Step-by-step explanation:

life-cycle adaptation would be like a tadpole growing legs.

physical adaptation would be a change in the animals body like wings for a bat.

reproductive would be beneficial for making offspring like a peacocks bright feathers that attract mates.

Behavioral adaptations are responses to external stimulus like heat.

So behavioral is the best option.
