Food Web

(differs from a food chain in that it has multiple organisms in each role)

commensalism: barnacle gets food, lives on whale, whale is not harmed

[tertiary consumer]

mako shark

humpback whale

[competition]

bottlenose dolphin

(fin)

mutualism: cleaner fish eats parasites off of shark.

[predator-prey]

[secondary consumer]

Swims in schools similarly to the mackerel, and are streamlined, similarly to the shark.

[decomposers like bacteria]

mackerel

Herring

bacteria recycle carbon, nitrogen, and energy for the herring to use

decomposers [after death]

[predator-prey]

[primary consumer]

shrimp

zooplankton

[many zooplankton are parasites]

phytoplankton

[producer]
