Explanation:
Dynamic aspects of an ecosystem are mineral cycles and energy flow. Mineral cycles are biogeochemical cycles through which there is exchange or circulation of nutrients in the biosphere.

Biotic components are living part of the environment which include producers, consumers and decomposers whereas abiotic components are non living part of the environment which include light, water, temperature etc.
