Food chains, trophic levels, and biomass

Food chains, trophic levels, and biomass

Food chain grass to rabbit to fox to eagle next to a biomass pyramid with trophic levels 1 to 4 labelled and bars getting narrower upward

A food chain shows who eats whom, and each step is a trophic level. In grass →\rightarrow→ rabbit →\rightarrow→ fox →\rightarrow→ eagle, the arrow means "is eaten by," so biomass and energy move in the direction of the arrow.
