Question

Differentiate hibernation and aestivation.

Hint:

Remember: Hibernation = Winter sleep, Aestivation = Summer sleep.

Answer 1

Concept: Hibernation and aestivation are adaptive strategies used by organisms to survive unfavorable environmental conditions.
Step 1: Differences.
\[ \begin{array}{|c|c|c|} \hline Basis & Hibernation & Aestivation
\hline Season & Winter & Summer
\hline Purpose & Escape cold conditions & Escape heat and dryness
\hline Examples & Bears, frogs & Snails, fishes
\hline Metabolic rate & Reduced & Reduced
\hline Environmental condition & Low temperature & High temperature and dryness
\hline \end{array} \]
Step 2: Conclusion.
Thus, hibernation occurs during winter, while aestivation occurs during summer to survive adverse conditions.
