producers, CONSUMERS, and DECOMPOSERS
A producer, or autotroph, is an organism that produces their own food through photosynthesis. A consumer or heterotroph are organisms that get their food and energy by eating or digesting other organisms. Decomposers are the waste manager of the ecosystem. They break down dead organic matter.
producers
phytoplankton
One of the major producers in the Arctic Ocean are phytoplankton. They are usually single celled organisms and use photosynthesis to create energy.
consumers
zooplankton
Zooplankton are tiny animals that feed off either phytoplankton or other zooplankton. Zooplankton are not the only consumer. In fact lots of the organisms are consumers. whales, sharks, seals, penguins, birds, and polar bears are only a few of the consumers in the arctic.
decomposer
scavengers and bacteria
Decomposers in an Arctic biome contain bacteria, the prime decomposers through the world. Mosses lichens, and fungi are also decomposers but things things take a long tie to decompose in the ocean because there is only a small window of temperatures that would allow activity. Scavengers also help clean up dead organisms.
