Killer whale food web

In this food web the producers that gives all the energy to the other animals are the seaweed and phytoplankton. Then comes the primary consumer which is the crab, zooplankton, and krill followed along with the secondary consumers. The fish, seagull, squid, penguin, and elephent seal. Then the top of the predators come, the kings of this food web. Blue whale, leopard seal, and the killer whale.

Mutualism is a type of symbolic relationship that helps both animals not just one. An example of mutualism is a pelican and dolphin working together to gather a horde of fish and trapping them so both of them are able to eat.

Parasitism is basically one animal benefiting off another while they get nothing in return. An example of that in the ocean would sea lampreys attaching themselves to sharks because they get a free ride and the shark gets no benifits.
