Question

In which zone of a marine biome does maximum photosynthesis takes place?

• A. Aphotic zone
• B. Abyssal zone
• C. Benthic zone
• D. Pelagic zone
• E. Photic zone

Answer 1

The correct option is E Photic zone

A. Aphotic zone is the zone of an ocean where no sunlight can reach.

B. Abyssal zone is the zone of an ocean which does not receive sunlight but contains consumers and decomposers.

C. Benthic zone is the lowermost zone of an ocean which is the bottom portion of the ocean.

D. Pelagic zone is also known as the open ocean zone which is not near the shore.

E. Photic zone is the zone of an ocean which receives sunlight and is sufficiently illuminated. This zone contains the photosynthetic organisms such as phytoplankton.

Hence the zone of a marine biome where most photosynthesis takes place is photic zone. So, the correct answer is 'Photic zone'.
