Given below are two statements one is labelled as Assertion (A) and the other as Reason (R). Assertion (A) : Phytoplankton grow in abundance in the limnetic zone. Reason (R): Limnetic zone is open water zone. Select the correct answer from the code given below: Code:

Question

Accepted Answer

Both (A) and (R) are true and (R) is the correct explanation of (A). The limnetic zone is the open and well-lit area of a freestanding body of freshwater, such as a lake or pond. The limnetic zone is the most photo- synthetically-active zone since it is the primary habitat for planktonic species. Because phytoplankton populations are densest here, it is the zone most heavily responsible for oxygen production within the aquatic ecosystem. Hence both (A) and (R) are correct and (R) is a correct explanation of (A).
