Different animals respond to changes in their surroundings in different ways. Taking one example each, explain "some animals undergo aestivation while some others hibernation". How do fungi respond to adverse climatic conditions?

Aestivation is known as summer sleep. Some animals like land crabs suffer from low metabolic rate as a response to high temperature and arid conditions so they aestivate. While on the other hand hibernation is known as winter sleep which is characterised by low body temperature, slow breathing and heart rate, and low metabolic rate as a response to low temperature. This is mainly shown by cold-blooded animals. Fungi produce resistant spores under unfavourable conditions which further enters the reproductive cycle when it receives favourable conditions.
