What can be said about the diversity of life in the high tide zone compared to that of the low tide zone?
Airida [17]

Answer:

B. There is less biodiversity in the high tide zone because the tidal changes make survival difficult.

Explanation:

The high tide and low tide zones are located on the seashore as the ocean water merges with land.

High tide zones are usually covered with water during high ocean tide while low tide zones are always submerged in water.

There is low biodiversity in the high tide zone because the tide here changes rapidly and organisms find it difficult to adapt. Organisms that inhabit here must be welll adapted to withstand peroids of high tides.
