Question

Wetlands are breeding places of mosquitoes. Even then they are very important for maintaining ecological balance. How?

Answer 1

Wetlands are marshy and swampy areas which get filled up during rains from runoff water, overflowing rivers, and channels
(i) By picking up extra water, wetlands prevent flooding.
(ii) They help in recharging ground water.
(iii) They purify runoff water because wetlands function as sedimentation traps.
(iv) A number of plants, animals and microorganisms reside in wetlands.
(v) They attract a number of birds, both local and migratory.
Their benefit of recharging ground water and preventing floods overweigh all other uses. Therefore, despite being breeding places of mosquitoes, maintenance of wetlands is an ecological necessity. Moreover, presence of mosquitoes and their larvae will attract their natural predators.
