The word "primary" means "first."

If that's true, what does primary consumer mean?

Hint: look carefully at the food chain!

• the first organism in a food chain

• the first organism that consumes something else for energy

Look carefully at the image. If energy is lost as it moves up the food chain, what trophic level has the most amount of energy?

• 1st level - producers

• 2nd level - primary consumers

• 3rd level - secondary consumers

• 4th level - tertiary consumers
