How do snails, seeds, bears, zooplanktons, fungi and bacteria adapt to conditions unfavourable for their survival?


#2

Ways to adapt to unfavourable conditions are:
(i) Snails undergo aestivation (summer sleep) to avoid summer related problems.
(ii) Bears undergo hibernation (winter sleep) during winter.
(iii) Zooplanktons enter a stage of suspended development called diapause.
(iv) Bacteria and fungi slow down their metabolic rate and form thick-walled spores to overcome stressful conditions. These spores germinate when the conditions become suitable.
