Diagram represents the numbers of organisms at trophic level food chain
PRODEUCERS CONSUMERS
Producers= capable of making their own food
First on a food chain
Consumers= not capable making own food
feed on other organisms

Flow energy sun, within ecosystem through each trophic level along food chains and finally out to atmosphere at heat loss for respiration
ENERGY LOSS IN A FOOD CHAIN
