Question

Which characteristic of coastal dynamics limits the abundance of aquatic organisms?

Consistent water depth levels
Consistent water temperatures
Varied tidal action
Varied water salinity

Answer 1

The answer is varied tidal action

Answer 2

The correct answer is "Varied tidal action".

Step-by-step explanation:

Varied tidal action refers to the presence of tides with different sizes and forces along a coast. This coastal dynamics characteristic limits the abundance of aquatic organisms because organisms must survive tidal action. Varied tidal action interferes with the adaptation of the aquatic organisms, as only a few organisms can survive this characteristic such as sea stars, sea urchins and sea cucumbers.
