Impacts: Distortion of food web
A combination of (a) mass viral infections and attacks on certain organisms; (b) contamination and pollution of food supplies which is inedible; and (c) uncontrollable hunting of exotic/rare/endangered species will lead to the disequilibria of species population. The next impact will be the imbalance in the ration of producers, consumers and decomposers in the ecology system, which consequently distorts the pattern of energy flow through the chain/web. This will bring to disruption of ecological food pyramid.
When ecological food pyramid is disrupted, insufficient consumption of food cause organisms deprived of energy, thus affecting the organism's metabolism of its biochemical activities. Then, growth and development of organisms will be affected, and leads to mass starvation and mortality in world population. On the other hand, particular species extinction occurred while its predators dominates, thus ecological niche in ecosystems change.
