assertion: Each step or level of the food chain forms a trophic level. Reason: The various components of the ecosystem are interdependent.
Dear student,
Please find below the answer:
Both assertion and reason are true but reason is not the correct explanation of the assertion.
A trophic level is the level of species in an ecosystem on the basis of the source of nutrition such as producers, primary consumers, secondary consumers, etc.
All components of an ecosystem- biotic and abiotic depend on each other. Any change in the no. of organisms at one trophic level leads to the disruption of the entire food chain which eventually leads to disruption in the ecosystem.
Hope this clears your doubt.
Regards.
