Answer 1

Answer:

Absorbing heat from the sun.

Explanation:

Penguins live in the south and north poles of the earth, where the temperatures are freezing. They need to retain body heat in any way possible, so they adapted to having black feathers on their back. The black feathers absorb more light and that, in turn, gets converted to more heat, and hence helps the penguin keep warm.
