View solution & NCERT explanation
Correct answer: A — If both assertion and reason are true and the reason is the correct explanation of the assertion.
NCERT confirms productivity varies among ecosystems and states “Primary productivity depends on the plant species inhabiting a particular area. It also depends on a variety of environmental factors, availability of nutrients and photosynthetic capacity of plants.” Both statements are true from NCERT. The Reason correctly explains WHY productivity varies - multiple interacting factors create different productivity levels in different ecosystems.
