Show transcript
Producers are organisms that can make their own food, including plants and some microorganisms.
Consumers (e.g. humans and other animals) cannot make their own food; they get their food by eating other organisms.
A food chain diagram shows the feeding relationships between populations of organisms.
The arrows in a food chain diagram represent transfers of biomass.
A change in the size of a population will affect other populations in the food chain.
