Briefly explain the following terms 1.Aestivation 2.huddling 3.hibernation?

1. Aestivation is a state of dormancy or inactivity that some animals enter during hot or dry periods to conserve energy and water. It is similar to hibernation but occurs in response to high temperatures rather than cold temperatures.

2. Huddling is a behavior in which animals group together closely for warmth and protection. This is commonly seen in social animals such as penguins or meerkats during cold weather to conserve body heat.

3. Hibernation is a state of dormancy that some animals enter during the winter months to conserve energy when food is scarce. During hibernation, an animal's metabolic rate slows down significantly, and its body temperature drops to conserve energy.

1. Aestivation: A state of dormancy entered by certain animals during hot, dry periods, characterized by reduced activity, metabolism, and water loss.

2. Huddling: A behavior exhibited by animals in cold environments where they gather together to share body heat and reduce heat loss.

3. Hibernation: A state of prolonged dormancy entered by certain animals during cold or food-scarce periods, characterized by significantly reduced body temperature, metabolism, and activity. Hibernation is initiated by physiological changes triggered by environmental cues such as decreasing day length and temperature.
