Question
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?

Answer

Some animals go into aestivation to avoid summer related problems (heat and dessication), eg. snails/fish.
Some animals go into hibernation to avoid winter related problem (extreme cold) eg. bear.
Fungi form thick walled spores and suspend their activities to respond to adverse climatic condition.
