Ecosystem
Introduction
Ecosystem is similar to a community. It consists of species, living organisms and the abiotic factors, their habitat. Living organisms includes animals, plants, insects, micro-organisms. For their habitat, they are the non-living nature which are soil, sunlight, water, precipitation. There are two types of ecosystem. Terrestrial ecosystem which is on the land and aquatic ecosystem which is under the water.
Over-breeding is the increase of offspring of a species to a excessive number. In dictionary definition, it means “to breed to excess especially without regard to the quality of the breeding stock”. There are various reasons of over-breed. The first one would be global effect, it is one of the main concern for the problem of over-breeding. Global warming changes the climate. Those are tolerant enough to survive can survive and increase the population; those who are not will decrease in number. This leads to the extinction of species. The lower trophic level will increase in population size. secondly, untreated pollution such as sewage and industrial discharge are toxic materials. When they leak to the environment, it will cause the same result as the global warming. Thirdly, Species are imported to a new place where they do not have predator and can adapted to the environment will have increase in the number of population. Fourthly, human abandon animals without concern would leads to the problem of over-breeding.
Over-breeding will interfere the ecosystem. For the environment, the over-breed species might damage the plants, destroy the shelter and breakdown food chain. In the living organisms, species in the same ecosystem might change their usual prey, decrease the initial resources, aboriginal living organisms might disappear and be edged out from the original habitat. Finally, biodiversity will be lost. The variability among living organisms from all sources including terrestrial, marine, other aquatic ecosystems, and the ecological
