Our planet is rich and beautiful.That part of the world, is home to a variety of flora and fauna, is called biosphere.For a better understanding of the processes of their interaction introduced the concept of ecosystem.It is a term that implies a relationship of living organisms with the conditions of their habitat.Each component of the system is linked with the others and, directly or indirectly dependent on them.Thus, even a slight disruption of the functioning of an object will cause an imbalance of the group.
What is an ecosystem?
Any ecosystem - the place of origin and development of life.No organism can grow in isolation: only in conjunction with other biological objects and environmental conditions possible its continued existence.
This concept has no size.That is, whatever the object in question, it is an ecosystem.For example, there is no difference whether the studied area of the ocean or a small overgrown pond, and maybe it's a pine forest, or the Gobi Desert.Both the first and second and third, any other - ecosystem.It is a term which coined the biologist, to be precise, phytocenology A. Arthur Tansley.As a part of this concept?Firstly, the system includes biogeocoenosis.It includes absolutely all the living organisms that live in the environment under study.Secondly, the abiotic component, all of the non-living, but it is absolutely necessary components: air, water, light.And thirdly - an inevitable part of the dead - already dead organic matter, or in other detritus.
Biogeocoenosis and ecosystem. their stability and change
Many sources indicate that the ecosystem - is synonymous biogeocoenose.Between these concepts there are no clear boundaries.As and between ecosystems, one can easily switch to another.It is in these areas people should be particularly careful and cautious: any, even the slightest interference can ruin a few species.
field of interaction of organisms with their environment and with each other, emerged without human intervention, - natural ecosystems.They are stable single unit, which is inherent in the concept of homeostasis.It characterizes the term sustainable development of all members of society.Homeostasis means the balance between the consumption of matter and energy and their release, the balance between the birth and death rates.For example, the ecosystem "fox-rabbit."If the number of hare "livestock" is growing, it inevitably grows and the number of predators, so as not to allow the plant to destroy the long-eared producers.The latter, in turn, synthesize organic substances from inorganic counterparts in all known photosynthesis.
ecosystem change.Artificial habitat base beings
Thus, any ecosystem of all the forces resisting any factors leading to disruption of its stable state.A known fact that the base of the more stable the more it food chain, the more it one for duplication.Any
, whether terrestrial or aquatic ecosystems, are modified over time.For example, the numerous shells that we meet on the shores of the seas: most of them have long been extinct due to destruction of their mollusk called Rapan.
Currently into use and includes artificial ecosystem - the "man-machine", "people business" and others.And if in these areas Homo sapiens still can control the processes taking place without harm to the result, the natural environment is not running.
