Question

What marine ecosystem contains the fewest producers?

Answer 1

The open ocean is the marine ecosystem that contains the fewest producers. This is because the open ocean has far fewer nutrients than other marine ecosystems, and there is no soil or ocean floor for producers to get nutrients from. In addition, there are sections of the open ocean that receive little sunlight, making it more difficult for photosynthetic producers to live there. The open ocean does have small producers such as algae, as well as some seaweed that can live in the upper levels of the open ocean that receive more sunlight. As a general rule, though, the open ocean has the fewest producers of any marine ecosystem.
