Biome

Trophic level
each step in the food chain
made up of organisms w/ important ecological wars
Producers (autotrophs)
Make there own food/glucose
Consumers (heterotrophs)
ingest food(glucose) to obtain chemical energy needed to build ATP
Decomposers
Breaks down dead organisms and returns nutrients to the soil
Food chain
show energy transfer from autotrophs to heterotrophs
