Organisms may avoid stressful conditions by suspending their activities for sometime. If they do it to aviod high temperature it is called ________and if they do it to avoid low temperature then it is called _________

Options

A. aestivation, migration
B. migration, hibernation
C. aestivation, hibernation
D. hibernation, aestivation

Explanation

To answer the question, we need to identify the terms associated with organisms suspending their activities to avoid high and low temperatures.

1. **Understanding the Concept**: We know that organisms can suspend their activities to survive unfavorable environmental conditions, particularly extreme temperatures. This is a survival strategy for many organisms.

2. **Suspending Activities for High Temperature**: When organisms suspend their activities to avoid high temperatures, this process is referred to as **estivation**. Estivation is a form of dormancy that occurs during the hot summer months, allowing organisms to avoid heat stress and desiccation.

3. **Suspending Activities for Low Temperature**: Conversely, when organisms suspend their activities to avoid low temperatures, this is known as **hibernation**. Hibernation is a state of dormancy that occurs during the cold winter months, allowing organisms to conserve energy when food is scarce and temperatures are too low for normal activity.

4. **Final Answer**: Therefore, the complete answer to the question is: If they do it to avoid high temperature, it is called **estivation**, and if they do it to avoid low temperature, then it is called **hibernation**.
