The marine biome a. is a large ecosystem, but not larger than some terrestrial ecosystems b. is characterized by four different zones c. has little species diversity d. covers a small portion of the earth’s surface select the best answer from the choices provided

The right answer is B.

The marine biome is distributed according to the depth:

littoral zone, or tidal zone, or intertidal zone, zone located between the tidal limits;

pelagic zone, up to 200 meters;

bathyal zone, from 200 to 3,000 meters;

abyssal zone, from 3,000 to 7,000 meters;

And sometimes a hadal zone, or ultra-abyssal zone, more than 7000 meters;

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
