Answer 1

Which of the following habitats is most unsuitable for primary productivity Pond

Answer 2

Cave  is most unsuitable for primary productivity

Explanation:

• Primary productivity refers to the organisms that are able to perform photosynthesis mostly the green algae

• If primary production must occur the organisms must be able to receive sunlight for the process

• Hence the production of photosynthesis mainly depends on the presence or the absence of sunlight  

• In ecosystems like meadow, forested river bank and pond there are possibilities of sunlight penetration and hence they can produce their own food  

• But in a cave there is no possibility for sunlight penetration hence cave is not a suitable place for primary production
