An organism that eats both plants and animals are know as a 

• Carnivore
• Omnivore
• Herbivore
• Decomposer

Autotrophs are organisms that produce their own food. Which do scientist classify as autotrophs?

• Chordates

• Herbivores

• Producers

• Carnivores

Trophic Levels show the

• what grade each organism has achieved in the ecosystem

• position that an organism occupies in a food chain - what it eats, and what eats it

• part of the triangle the organism likes the most

• elevation the organism likes to live in

• The mass of nonliving organisms in an area or ecosystem at a given time

• All the waste produced by organisms in an area

• The energy in an ecosystem

The role of decomposers in an ecosystem is to

• break down once living things from all levels of the ecosystem to recycle nutrients back to producers

• break down only top level consumers to recycle nutrients

• break down only producers to recycle nutrients

• give energy to all levels of the ecosystem

Heterotroph means

• the organisms get their energy from eating other organisms

• the organisms make their own food from photosynthesis

• the organims get energy from breaking down once living things

Which level would have the most biomass?

• Producers

• Primary consumers - herbivores

• Secondary consumers- carnivores

• Quaternary consumers- Apex Predators
