Adiver 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

Many photosynthetic organisms and large amounts of light.

Explanation:

The surface layer of the ocean consists of epipelagic zone. This zone extends from the surface to 200 meters. This zone receives maximum sunlight. As a result of this it favors the process of photosynthesis of the plants. Hence, the diversity of plants is more in this zone also this will favor the survival of the zooplanktons and animals which are dependent on plants for their food requirements.        

the reason the two sea urchins don't compete with each other for food, resources, etc. is because the urchins have adapted to the environment but they have also adapted to each other. this is most likely because the genes of the sea urchins.
