Question

Which statement best describes how varying conditions in coastal areas affect the abundance of aquatic organisms living there?

Fewer aquatic organisms live in coastal areas because the tides require organisms to constantly adapt to changing conditions.
More aquatic organisms live in coastal areas because organisms swept away during high tide can easily return to land during low tide.
More aquatic organisms live in coastal areas because tidal processes help maintain a more constant water temperature compared with other ocean areas.
