What is the introduction of endangered ecosystem?

Answer 1

An endangered ecosystem is a natural environment that is threatened with collapse and disappearance due to human activity, pollution and species extinction or overpopulation among other factors. Living and nonliving entities interact, form interdependent relationships and exchange energy and matter in ecosystems that can be as large as the planet or as small as a fishbowl. When the interdependence between an environment's species and physical and chemical factors is disrupted, the ecosystem becomes endangered and can possibly disintegrate completely. The consequences of ecosystem collapse include mass extinction, species populations surging beyond control, disruption of human food supplies, erosion, flooding, acceleration of climate change and the disintegration of large regions of the natural environment.

There are many natural and human causes of an endangered ecosystem, causes that often disrupt an ecosystem's food chain and physical environment. Overfishing of a particular aquatic species such as sharks or bluefin tuna can detrimentally impact a food chain by depleting large predators that keep smaller species populations from surging out of control. Without large predators, many species will breed beyond the immediate environment's ability to support them thus resulting in resource and food diminution and an endangered ecosystem.

When the resources of the current ecosystem are exhausted, an overbred species may then move to a new environment where it may become invasive and destructive. Species can also be introduced into an ecosystem by man in an effort to control the population of a native animal or insect but have a disruptive effect instead.
