Question

MEDAL + FAN

Which of the following best explains why the diversity of organisms decreases as you move from shallow seas to deep oceans?
a. The levels of oxygen in the deep ocean are too high for many organisms to thrive.
b. The low temperatures of the deep ocean would freeze most organisms.
c. The salinity of the deep ocean is too high for most organisms to live.
d. The lack of sunlight in the deep ocean limits the types of organisms that can survive.

Everyone says it's D but I saw another post where someone said it wasn't right, but idk. I'm stuck between B/C/D.

Answer 1

The lack of sunlight in the deep ocean limits the types of organisms that can survive.

Answer 2

Thanks!

Answer 3

This is a dumb question, we know so little about the deep ocean I don't think we can legitimately say anything about the diversity of life there.
