What is true about the ocean life zones?
10 points

Because of its exposure to sunlight, photosynthetic organisms are at the bottom of the food chain in the lighted zone.

Organisms are not able to survive in areas that are not exposed to light.

The same organisms are present in both the lighted and dark zones of the ocean.

Animals prefer the dark zone of the ocean.

Because of it's exposure to sunlight, photosynthetic organisms are the bottom of the food chain in the lighted zone

Explanation:

In the sunlit zone there is enough sunlight for photosynthesis to take place, photosynthetic organisms like Plankton produce food. The use the light energy from sunlight with carbondioxide and water to produce food and release oxygen. The largest oxygen percentage of the Earth is produced from the ocean(about 90%) which is produced by Plankton. Plankton serve as the primary producers in this zone, many animals also live in this zone because of food availability.

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.
