Question

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

Answer 1

Adaptations to unfavourable conditions in the following organisms:

i. Snails: Snails undergo aestivation to avoid summer-related problems such as heat and desiccation.

ii. Seeds: The seeds undergo dormancy to tide over adverse environmental conditions. They reduce their metabolic activity and remain quiescent till the suitable environmental conditions return.

iii. Bears: They undergo hibernation during winters to escape harsh winter conditions.

iv. Zooplankton: Zooplankton species in lakes and ponds enter diapause which is a stage of suspended development.

v. Fungi: In fungi, various kinds of thick-walled spores (zygospores) are formed which help them to survive in unfavourable conditions. The spores germinate on the return of favourable conditions.

vi. Bacteria: Bacteria form thick spores (cysts) which help them to survive under unfavourable conditions.
