Question
Explain the following with suitable examples.
What are the differences between the flow of matter and of energy in an ecosystem? Why?
Solution
| Energy flow in an ecosystem | Flow of Nutrients in an ecosystem |
| 1. The flow of energy in an ecosystem is unidirectional. | 1. The flow of nutrients in an ecosystem is cyclic. |
|
2. Energy is transferred from producers to consumers via one trophic level to the next. |
2. Primary consumers pass on nutrients from producers, while primary consumers pass on nutrients to secondary consumers. Only decomposers provide nutrients in a cyclical manner. |
| 3. Some part of the energy which is not utilized is thrown into the atmosphere. | 3. Nutrients are not destroyed in the ecosystem. |
