- The pelagic zone of the ocean is the area of the ocean that is neither close to the bottom nor close to land. There are a wide variety of organisms that inhabit the pelagic zone. Phytoplankton float along the surface, using photosynthesis to produce food. Zooplankton are tiny organisms that float in the surface waters and feed on the abundant phytoplankton. Krill, small crustaceans, also feed on phytoplankton. They display vertical migration in which they swim at deeper depths during the day and then come up to the surface waters at night to eat.

Dead zones: algal blooms consume oxygen, kills shellfish and displaces fish. Poisonous algae and countless plants and animals have invaded harbor waters and disrupted the local ecological balance. Destruction of coral reefs. Of the seventeen major world fisheries, four are depleted and the other thirteen are either fished to capacity or over-fished. Ghost nets: lost or discarded fishing nets keep on fishing. Nitrogen and phosphorus from sources such as fertilizer, sewage and detergents, enter coastal waters.

Kelps and corraline algae can be found along the lower intertidal and subtidal zones. ? The lower intertidal is dominated by seaweeds. The first stage of ecological succession in the rocky intertidal is the establishment of bacteria and microscopic algae. Green, brown and red algae on the upper intertidal are able to fix nitrogen from the air. The effect of a keystone species can easily be judged by how abundant it is.arrow_forward
