Food chains and trophic levels

Food chains and trophic levels

Food chain with grass, rabbit, fox and eagle labelled as producer, primary consumer, secondary consumer and tertiary consumer, with decomposers recycling nutrients back to grass

A food chain shows how food, biomass and energy pass from one organism to another. The arrow means "is eaten by", so the arrow points from the food to the feeder.
