Multiple choice

In extremely arid environments, such as deserts or polar regions, what adaptation strategy do organisms employ to conserve water and survive in conditions of limited moisture?

  1. Dormancy

  2. Hibernation

  3. Estivation

  4. All of the Above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Organisms in extremely arid environments employ a combination of strategies to conserve water and survive in conditions of limited moisture. They may enter dormancy, hibernation, or estivation, which are states of reduced metabolic activity and water loss.
