It is not easy to justify the existence of mosquitoes. Mosquitoes seem to serve no purpose other to annoy us, transfer diseases and produce more mosquitoes. from the mosquitoes' point of view, their purpose is to make more mosquitoes and survive. Mosquitoes are part of the ecosystem. Mosquitoes serve as a source of food to fishes, frogs and other animals that eat them.
With 3,500 species of mosquito, , one would trust that they would all be on the chase for human blood. Shockingly, there are just a hundred couple of species that nibble or are of any sort of threat to people. As it were, out of the couple of hundred species, there are a chosen few that spread maladies and contrarily influence humankind. Is that why they all appear to appear to be identical very close?
Likewise, numerous researchers trust that wiping out a species of mosquito would leave a biological scar that would incite ruin—an exceptional imbalance. This speculative imbalance is accepted to leave predators without prey and plants without pollinators.
From this viewpoint, a mosquito's motivation is to survive and make more mosquitoes, while mosquitoes in general have no reason. It's great to note, however, that numerous winged animals and different creepy crawlies eat mosquitoes and that numerous fish eat mosquito hatchlings. For these animals, mosquitoes fill in as food.
