aphotic zone
benthic zone
limnetic zone
littoral zone
Draw a food chain for Puget Sound using these organisms and abiotic components. Some possible organisms to include in the food chain are: herring, marine bacteria, people, phytoplankton, pteropods, krill, oysters, Dungeness crab, salmon, Orcas.
Food chains are typically short in the tundrabecause primary production is lower than in mostother ecosystems.
