Ecosystems

What is ecosystem?

In this video i show what is an ecosystems?various kinds of lite supporting systems like the forests, grassland and, lakes, rivers, mountains, deserts and estuaries show wild in their structural composition and alike in the fact that they consist of living entities interact their surroundings exchanging matter and energy, How do the rent units like a hot desert, a dense evergreen forest, the Antarctic shallow pond ditter in the type of their flora and fauna, how ey derive their energy and nutrients to live together, how do the thence each other and regulate their stability are the questions th answered by ecology The term ecology was coined by Earnest Haeckel in 1869, lt thom the Greek words out as home t lens study so ecosystem deals with the study of organisms in their natural home interactive their surroundings. The surroundings or environment consists other living organisms called biotic components and physical fact called abiotic components interacts with other For example, how a small insect in a forest animals, plants, soil, air or water is studied in its ecology.

The surroundings or environment consists other living organisms called biotic components and physical fact called abiotic components interacts with other For example, how a small insect in a forest animals, plants, soil, air or water is studied in its ecology. Thus ecosystem science that studies such interactions and relationships of organism or a group of organisms ecosystem Modern ecologists believe that an adequate definition of must specify some unit of study and one such basic unit described (1935) ecosystem An ecosystem is a self-regulate biotic communities of species interacting with one a and with their non-living ironment exchanging energy Now ecology is often defined as "the study of ecosystem.

Some keyconcept of eco system:

1)An ecosystem is an integrated consists of integrating plants, animals and microorganisms whose survival depends an plants, animals and microorganisms biotic and abiotic upon the maintenance and regulation of their structures and functions.

 2)The ecosystem is a unit or a system which is linked number of sub-units, that are all directly or indirectly with each other.

 3)They may be freely exchanging energy and matter from outside an open ecosystem or may be isolated from outside-a closed ecosystem. 

4)Life on the earth is sustained by the flow of energy from the sun and cycling of nutrients through the ecosystems.

5) Energy flow and nutrient cycling through ecosystems are getting
