LOCAL ECOSYSTEM

By: Deepthi 7C

The local ecosystem that I have chosen is my garden. In my garden there are earthworms, caterpillars, shrubs, roses, tulsi plant, leaves, grass and other flowers. Ecosystems are made up of biotic and abiotic factors. Biotic factors are living and abiotic factors are non-living. The biotic factors in my garden are the plants and animals and the abiotic factors are soil, water, air, rocks, sunlight. Ecosystems also have food chains and food webs, a food chain is a series of organisms each dependent on the next as a source of food. Food webs are a system of interlocking and interdependent food chains.

Everything in my garden is interconnected and needs the other plants/animals in order to survive. Caterpillars eat the plants and then a bird eats the caterpillar. Then a bigger bird eats the smaller bird and then an eagle eats the bigger bird. When the eagle dies, the decomposers eat the eagle. Even small changes within an ecosystem can affect the entire ecosystem. A mutualistic relationship between species in an ecosystem allows for the ecosystem to thrive, but the lack of this relationship could lead to the collapse of the entire system. Also, if some animals die, the other ones will not be able to survive because they will have no source of food. That will cause the food chain to break and the ecosystem will not be balanced.

This is a picture of how my garden looks.
