Answer: There is more diversity in the splash zone because there are fewer predators.
There is more biodiversity in the splash zone because there are more nutrients available.
Splash zone is also known as intertidal zone which is present in the coastal region. It remains exposed to air under the effect of low tides and remains submerged due to high tides. Submerged zone is a zone of marine habitat that always remains covered with water. This zone remains near the bottom bed of the aquatic body.
There is more diversity in the splash zone because there are fewer predators: The splash zone exhibit shallow water which larger fish and other predators find not suitable for catching their prey, therefore, this facilitates the growth of organism living in splash zone.
There is more biodiversity in the splash zone because there are more nutrients available: The splash zone exhibit shallow water which facilitates the sunlight, carbon dioxide from atmosphere to efficiently penetrate the water cover and reach to the plants. Hence, support more growth of vegetation as compared to submerged zone. Also, this zone receives direct oxygen and other atmospheric gases necessary for the survival of aquatic organisms.
