The chemical spill, which is sprayed on the plants kill the insects, when dissolved in water body kills the aquatic animals. The effect is seen mostly in higher trophic level organisms because of biomagnification. Biomagnification is a phenomena in which an undigestable toxic substance enters into the food chain when one organism being eaten up by other. At the top higher level of the food chain accumulates toxic substances from chemical spill and results in death and extinction of species. Therefore, causes loss of biodiversity from the ecosystem.
