Which of the following best explains why the diversity of organisms decreases as you move from shallow seas to deep oceans?
Answer

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

The levels of oxygen in the deep ocean are too high for many organisms to thrive.

The low temperatures of the deep ocean would freeze most organisms.

The salinity of the deep ocean is too high for most organisms to live.

I think none of the options have much to do with diversity in the deep sea.

We tend to see diversity in life forms only when it is advantageous - that is, when there are many different niches or microenvironments in a small area. Then specialising in one particular niche is advantageous to the organism.  By contrast the deep sea is a rather homogenous environment - dark, cold, lots of pressure. I think that is probably a more significant limiting factor on the diversity than any of the options you're given.

the first option

anonymous · Answer

All depends on producers which are plants... With the depth, sunlight limits its value and after a threshold value of sunlight plant's survival is not possible... So when there is no plant population then the consumer population will also decrease.
so the first option is correct.
