Question

The intertidal zone is home to an abundance of aquatic organisms, like the barnacle, that can survive periods where they are not underwater. What type of tide would most likely decrease the abundance of aquatic organisms, and why?

Answer 1

Spring tide because it creates a large difference between high and low tides, so the organisms are in extreme environments

Answer 2

Downwelling because it creates a cold environment that is not suitable for all aquatic organisms
