Question

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

Explanation:

The littoral zone is closer to the shore, receiving more sunlight which supports photosynthesis by plants and algae, providing food and habitat. It also has more nutrient - rich runoff from land, creating a more favorable environment for a wide variety of organisms compared to the benthic zone which is often deeper, darker, and with less nutrients and light.

Answer:

The littoral zone has more sunlight, nutrients from runoff, and thus more favorable conditions for a greater variety of organisms compared to the benthic zone.
