Why are living organisms more common in the littoral zone than in the benthic zone? a. the benthic zone has less light penetration. b. the littoral zone has a variety of plants. c. the littoral zone provides more resources. d. all of the above select the best answer from the choices provided a b c d

d. All the above

The littoral zone is the part of water body that lies close to the shore, whereas the benthic zone is the deepest region of the water body that is the bottom bed and sub surface layers of water. The organisms that live in the benthic zone are called as benthos.

The littoral zone is directly exposed to the sunlight but the benthic zone receives very little sunlight as a consequence of this the diversity of plant is more in the littoral zone than in the benthic zone. The littoral zone receives fresh atmospheric oxygen which allows the growth of more numbers of plants and animals whereas the benthic zone does not exhibit fresh atmospheric oxygen hence, littoral zone supports more plant growth than the benthic zone.
