Question

Which of the following best explains why the diversity of organisms decreases as you move from shallow seas to deep oceans? (2 points)

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.

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

Answer 1

Ooh this one is tricky. My first thought is that it's because of the lack of sunlight..Most organisms that live in the deep sea have adapted to the lack of sunlight.

Answer 2

The water is also very cold and salty in the deep sea..but what's the correct answer here? Hmm.

Answer 3

Well that's an interesting metaphor

Answer 4

Lol I think I'll have to memorize it. So back to your question, my gut is saying D. What do you think?

Answer 5

Ok, let's see what happens :)

Answer 6

Oh I forgot to say, but another reason why I think it's D. is because having no sunlight drastically minimizes breeding. This goes right along with the part in the question where it says "diversity". That's my reasoning anyway :P

Answer 7

Because of no sunlight, most organisms have evolved to be hermaphrodites..which is something that only happened because of the lack of sunlight.

Answer 8

Oh poo, really? Well, I'm glad you trusted your gut. Sorry mate.

Answer 9

So what was the correct answer? You probably don't remember it, but I figured I'd ask anyways.
