Question

Why are living organisms more common in the littoral zone than in the benthic zone?

Answer 1

On edge

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.

Answer 2

Living organisms are more common in the littoral zone than in the benthic zone simply because the littoral zone is shallow and well-lit water that is obviously nearer to the shore compare to benthic that is at the very bottom of the aquatic biomes and is made up of sand and organic sediments.
