How do organisms like fungi, zooplanktons and bears overcome the temporary short-lived climatic stressful conditions? Explain.

Text Solution

Verified by Experts

Fungi : They form thick-walled spores which help them survive in unfavourable conditions. On availability of suitable environment, these germinate.
Zooplankton : Under unfavourable conditions, these species in lakes and ponds enter diapause, a stage of suspended development.
Bears : In extreme low temperature, they escape winter time, i.e., they hibernate
