Involves free living organisms that may only encounter each other only once. -Community - -Assemblage of organisms living in the same area at the same time. -Trophic Level - -Rank in feeding hierarchy -Producers - -1st Trophic level Autotrophs Cyanobacteria, algae, phytoplankon, and grasses Capture solar energy and use photosynthesis to produce sugar -Consumers - -2nd trophic level Zooplankton, grazing animals like deer or cattle, insects Consume producers -Secondary Consumers - -3rd trophic level fish, rodents, wolves prey on primary consumers -Tertiary Consumers - -4th trophic level [Show More]
