     An ecosystem is the union of the organisms and abiotic factors in an area. It may exist in a sand dune, a tidepool, a coral reef, or even a vacant lot. Any environment that contains minerals, water, air, plants, animals and microorganisms can be considered as an ecosystem.

     It can be also defined as large areas that contain groups of organisms living and interacting with one another which share biotic factors.

     Life is abundant on planet Earth. Our planet itself is a big ecosystem where, human beings, plants, animals and other organisms interact and depend on one another in order to survive and consist of smaller-range ecosystems.



What is the use a house if you donít have a decent planet to put it on?

~Henry David Thoreau
