How do tides affect the organisms living in intertidal zones? A. The mechanical forces of the waves can dislodge the organisms from their habitat. B. Only plants live in intertidal zones because the animals float away with the waves and never return. C. No organisms live in intertidal zones due to the tumultuous environment. D. The mechanical forces of the waves keeps the organisms clean.

A. The mechanical forces of waves can dislodge the organisms from their habitat.

Explanation:

As the tides rise and fall, the salinity (salt concentration) constantly changes. Animals living in the intertidal zone must be able to tolerate wide salinity variations. If sufficient nutrients are available, intertidal animals reproduce rapidly, so they constantly compete for space, light, and food.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.
