Aquatic ecosystems are susceptible to many chemical changes. Usually if the chemistry of a “healthy” ecosystem changes, signs of this change will include sensitive organisms quickly declining in number or disappearing. These types of organisms are called .

This biome is the driest; it only receives 50cm of rainfall a year about 10% of the rainfall in the rainforest. Its plants and animals have to survive in an environment with little water and dramatic temperature changes from day to night. Some animals and plants may find if difficult to adapt, but reptiles and cacti thrive in these conditions.. http://www.neok12.com/php/watch.php?v=zX0215667004445d05420545&t=Ecosystems.

Biomagnification. is the process by which matter becomes concentrated in living things in a food chain.. Moving up the Food Chain . DDT provides one example of the effects of . biomagnification. in an ecosystem. DDT is a chemical that was widely used to kill plant–eating insects. Some chemicals break down over time, but DDT does not. DDT collected in water and soil, was absorbed by living things, and moved up the food chain. The diagram shows how DDT became magnified in a wetland ecosystem. It entered through tiny organisms called zooplankton, which absorbed DDT from the water.. (A) . Abiotic. component.
