Trophic levels are represented by 

• squares
• circles
• pyramids
• lines

In the energy pyramid here, how much of the energy in each level gets lost as heat or used by the organism for survival?

• 80%
• 90%
• 10%
• 20%

A producer

• Eats grass

• Makes its own food

• Does not need food(energy)

• Is a primary consumer

A primary consumer

• makes its own food

• eats other animals

• is a carnivore

• consumes the producer

A secondary consumer

• Only eats meat

• Only eats plants

• makes its own food

• eats the primary consumer

The first trophic level is

• Carnivore

• Producer

• Primary Consumer

• Herbivore

tertiary consumers

• Eat the primary consumer

• Eat plants and animals

• Consume the producer

• eat the secondary consumer

How much energy is moved from one trophic level to the next trophic level?

• 100%

• 1/2

• 10%

• 25%
