Question

Hibernation and aestivation are examples of which response to environmental stress?

Options

• Regulate

• Migrate

• Suspend

• Conform

Answer 1

Suspend (or dormancy) is a response where organisms reduce their metabolic activity dramatically during unfavourable environmental conditions. Hibernation occurs during extreme cold, while aestivation occurs during extreme heat and dryness. Both strategies allow organisms to conserve energy and survive periods when resources are unavailable.
