Detailed explanation-1: -Bacteria break down (or decompose) dead organisms, animal waste, and plant litter to obtain nutrients. But microbes don’t just eat nature’s waste, they recycle it. The process of decomposition releases chemicals (such as carbon, nitrogen, and phosphorus) that can be used to build new plants and animals.

Detailed explanation-2: -An overabundance of nutrients-primarily nitrogen and phosphorus-in water starts a process called eutrophication. Algae feed on the nutrients, growing, spreading, and turning the water green. Algae blooms can smell bad, block sunlight, and even release toxins in some cases.

Detailed explanation-3: -Dead zones form when the algae die, sink to the bottom, and are decomposed by bacteria-a process that strips dissolved oxygen from the surrounding water. Dense algal blooms also block sunlight, which prevents underwater grasses from growing.

Detailed explanation-4: -When algae die, they are decomposed by bacteria which in this process consume oxygen so that the water can become temporarily hypoxic. Oxygen depletion, or hypoxia, is a common consequence of eutrophication, both in fresh water and seawater.

Detailed explanation-5: -Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle. Significant increases in algae harm water quality, food resources and habitats, and decrease the oxygen that fish and other aquatic life need to survive.
