The role of nature in human life can not be overestimated: it is for us both material and spiritual significance. Many people do not even think about the fact that their home - this is pure ecological system: mother nature gives man shelter, clothing, food, and so on. What is an ecosystem?

Ecosystem (ecological system) called biosystem, which entirely consists of:

· Community Of Living Organisms;

· Their Habitat;

· Their Mutual Metabolism And Energy.

The typical example of an ecosystem is a pond. It is a natural community - dwelling fish in it, micro-organisms, plants and invertebrates.
