being to take over underwater ecosystems. Usually, nitrogen supply is short in coastal ecosystems, as it puts a limit on the creation of organic matter by phytoplankton. Phytoplankton are small plants at the bottom of the food chain. When a certain ecosystem has a slight increase in nitrogen, phytoplankton population numbers grow drastically, which has a result of an algal bloom, and eventually destroys the state of equilibrium between the environment and its resources. Bacteria that is oxygen consuming eat the plankton that die and sink slowly to the ocean floor. When there is a bigger amount of plankton sinking, the bacteria uses oxygen more quickly than the water layers above it can replenish. In a result, this creates low oxygen conditions, as they are unsuitable for plant
