Question

In which zone of a marine biome do organisms need to be adapted to alternating dry and wet conditions as tides recede and come in?

• A. Neritic zone
• B. Oceanic zone
• C. Benthic zone
• D. Pelagic zone
• E. Intertidal zone

Answer 1

The correct option is E Intertidal zone

A. Neritic zone is the zone of the ocean that extends from the shore up to a depth of about 200 m.

B. Oceanic zone is the zone where the depth of water is equal to or more than 200 m.

C. Benthic zone is lower most zone at the bottom of a water body.

D. Pelagic zone is also called the open ocean zone. It is an open part of the ocean.

E. Intertidal zone is also known as littoral zone. It adjoins the shore and extends down to a point called the light compensation level, where the rate of photosynthesis equals the rate of respiration.

Hence the zone of a marine biome where organisms need to be adapted to alternating dry and wet conditions as tides recede and come in, is Intertidal zone as it adjoins the shore.

So, the correct answer is 'Intertidal zone'.
