Water temperatures which are important in all biological systems influence aquatic environments; this includes organic chemistry and the growth and death rates of aquatic life. Warmer climates and higher amounts of nutrient concentrations accumulate competition between phytoplankton and cyanobacteria in favor of cyanobacteria, which upsets the balance of aquaculture. (Depla et al, 2009). Plankton is a key source of food for larger animals. Phytoplankton is the first link in the food chain. They are known as primary producers because they produce the earliest forms of food. The disappearance of plankton would certainly affect the food chain, but there's another problem if phytoplankton were to disappear: it provides most of the atmospheric oxygen. As invasive species increase, important elements of aquatic ecosystems are being reduced and biodiversity is threatened. Biological ecosystems are moving into unnatural waters due to climate change, resulting in overpopulation and competition that create an unhealthy environment and bionetwork. Aquatic ecosystems have a specific buffering capacity, however once these buffering systems reach their maximum capacity, significant and often rapid ecosystem changes can occur that affect water quality (Murdoch, 2000). The complexity of aquatic ecosystems e
