PRODUCERS AND CONSUMERS
FOOD CHAINS

Food chains show how one living thing is the food for another.
Energy passes along a food chain from producers to consumers as one member of the chain eats the next.

Seaweed is a producer. It produces food by photosynthesis.

Periwinkles are called first consumers because they eat weed.

Herring gulls are called second consumers, because they eat periwinkles.

Seaweed --> periwinkle --> herring gull
This is an example of a food chain.
