Solution
The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- Phytoplankton is the foundation of the aquatic food web. They are the primary producers in marine ecosystem.,
- In a marine aquatic ecosystem, the biomass of phytoplankton(producers) at any given time, is lower than the biomass of zooplankton (primary consumers) because Phytoplanktons are consumed almost as rapidly as they are formed and thus have shorter life spans.
- Hence Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
- So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
