What are the component of ecosystem |
| Answer» An ecosystem has two types of components, viz. biotic component and abiotic component.Abiotic ComponentAll the non-living things make the abiotic component of an ecosystem. Air, water and soil are the abiotic components.\tAir provides oxygen (for respiration), carbon dioxide (for photosynthesis) and other gases for various needs of the living beings.\tWater is essential for all living beings because all the metabolic activities happen in the presence of water.\tSoil is the reservoir of various nutrients which are utilised by plants. Through plants, these nutrients reach other living beings.Biotic ComponentAll living beings make the biotic component of an ecosystem.\tGreen plants play the role of producers; because they prepare the food by photosynthesis.\tAnimals and other living beings play the role of consumers; because they take food (directly or indirectly) from plants.\tBacteria and fungi play the role of decomposers; as they decompose dead remains of plants and animals so that raw materials of organisms can be channelized back to the environment.\xa0 | |
