Relationships Among Marine Organisms

"Marine Food Web"

During the food web activity that my class did, I played the role of the benthic fish. This is an organism that lives at the bottom of the ocean. This organism eats crabs, worms, shrimp, mollusks. Larger fish, such as haddock and catfish mainly eat benthos as well as penguins. If this organism were to disappear, it would not affect and other organism that is at a lower spot on the food chain. This is because nothing at the bottom of the food chain will eat benthic fish, only organisms that are higher on the food chain will. The organisms that will be affected include penguins, whales, sharks, etc. This means that the neuston ecosystem will not be affected. 

"Phytoplankton"

Phytoplankton are very important to marine food webs because they are its foundation. They are the primary producers, meaning that everything feeds off of them or off of organisms that do. Neuston refers to organisms that float on top of water or live under the surface. These organisms consist of beetles, spiders, bacteria, protozoans, and certain species of fish. The neuston ecosystem covers up about
