Explain why there is greater biodiversity in the littoral zone than there is in the benthic zone.

Answer:

The littoral zone has a greater biodiversity than the benthic zone because the littoral zone can support plant life. The benthic zone has less light penetration than the littoral zone, so plants cannot thrive in it. The variety of plant life in the littoral zone provides a habitat and food resources for other aquatic animals, which accounts for the greater biodiversity of the littoral zone.
