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

Answers

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.

Answer:

Onedge

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.

The Y chromosome is passed on from one generation to another in sons as sons have one Y chromosome and one X chromosome while daughters have two X chromosome one from the father and the another one from the mother.

It is convenient to study the Y chromosomes in male to identify the family background.
