Scientific consensus supports the idea that living organisms require oxygen. Then, a scientist discovers a type of bacteria that
metabolizes sulfur instead of oxygen, and thus survives in environments without oxygen. The scientist concludes that a diverse group of many different organisms could live in an oxygen-free environment. Why should are some scientists skeptical of the scientist’s results and conclusion?
The answer is Habitat. The brackish water environment is formed due to the mixing of fresh water from the river with the salty waters of the ocean. This habitat is significant for fishes that come to spawn and feed. Crabs, mosquitoes and birds can also be found in this environment.
