ekosistem

ekosistem

An ecosystem is the term applied to the interaction of a community of different living (organic) species - plants, animals and micro-organisms - with non-living (or inorganic) factors, such as atmospheric gases, temperature and light. When the balance of an ecosystem is changed - by the introduction of new elements or dramatic rises in one or more of them - the normal functioning of the ecosystem can be disrupted.
