A diver is swimming near the surface of the ocean. What would she most likely observe, in terms of the numbers of photosynthetic organisms and light conditions?

Few photosynthetic organisms and very little light

Many photosynthetic organisms and very little light

Few photosynthetic organisms and large amounts of light

Many photosynthetic organisms and large amounts of light

The last one is correct

The correct answer is Many photosynthetic organisms and large amounts of light

Photosynthetic organisms live in upper parts of oceans near the surface because they need light. As you go down the number is reduced and light stops penetrating the surface, making the bottom of oceans completely dark and only organisms that feed on other organisms or on dead organisms survive.
