| Environment factor (s) that characterize the habitat of ecosystem is/are |
| a) | Abiotic components | b) | Biotic components |
| c) | Both (a) and (b) | d) | Temperature |
| (d)The most important elements that lead to so much variation are temperature, water, light, soil. Physio-chemical components alone do not characterize the habitat of an organism completely. It includes biotic factors also. So for characterization of habitat both abiotic and biotic components are needed |
