How are seamounts able to support diversity?​

A seamount is a large geologic landform that rises from the ocean floor but that does not reach to the water's surface

Explanation:

It is able to support diversity because many deep-sea animals, such as corals and sponges spend most of their lives permanently attached to rocks. As opposed to a flat seafloor, seamounts rise off the ocean bottom and interact with water flowing around them. These water currents can wash off sediment on a seamount, exposing rocks that are ideal habitat for animals that require hard substrate to grow and attach.

Also, because these animals cannot move around to find food, they are dependent on ocean currents to bring their food to them. The strong currents running over a seamount can deliver animals living along its flanks with a constant supply of planktonic food.  Nutrients like nitrates and phosphates, which are critical to the growth of phytoplankton, are lifted from the deep to the sunlit surface waters. These nutrients fuel an explosion of planktonic plant and animal growth and attract larger animals such as whales, sharks, tunas, and seabirds to a veritable feast.
