How is the balance in the environment maintained?

1.	How is the balance in the environment maintained?
Answer» 1. Plants use substances in the soil for their growth and when plants and animals die the microorganisms decompose them and this added to the substances goes back to the soil once again. 2. Similarly the water cycle maintains a continuous supply of water for all the living things. 3 . Living things take in oxygen and give out carbon dioxide while breathing. The plants take in carbon dioxide and give out oxygen while preparing their food. Thus oxygen gets added to the air. There are several other such cycles which go on in nature due to interaction amongst living things. When such interactions and cycles go on uninterrupted continuously, they help in maintaining the food chain. Due to this, environmental balance is maintained.
