How do snails, seeds, bears, zooplanktons, fungi and bacteria adapt

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

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.
