Solution
The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
GFC is a major conduit on energy flow in an ecosystem is a correct statement as we know that a GFC starts at a producer and ends at secondary or tertiary consumer while a DFC starts with detrivores acting on detritus. As we are aware that no detritus is present inside the aquatic ecosystem so DFC can't be a major conduit of flow of energy it is always the GFC.DFC may be connected with GFC at some levels because some of the organisms of DFC are prey to GFC animals. So, interconnections do exist.Since both the statements are true but they don't explain each other.So, the correct answer is 'Both assertion and Reason are correct but Reason is not the correct explanation for assertion'.
