Energy transfer is said to be unidirectional where biochemical transfer is said to be cyclic? Why. |
| Answer» Solution :The FLOW of energy is unidirectional because the energy LOST as heat to the environment can.t be reutilized by plants for photosynthesis. Energy DECREASE at each tropic level (10% of previous level). Hence it can.t be reused again. Whereas biochemical transfer is CYCLIC because nutrients utilized by plants and animals are returned to environment after the death of organisms. | |
