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 trophic pyramid is a triangular shape because

• 90% of energy is lost to heat, movement, and survival, and only 10% of energy goes to the next level

• People see the top of the pyramid so it is important to know the keystone species.

• 10% of energy is lost to heat, movement, and survival, and only 90% of energy goes to the next level

• the top of the pyramid is the pinnacle organism of an ecosystem

Producers obtain their energy by

• the process of hunting for prey

Omnivores make their energy by

• eating plants

• eating animals

• eating plants and animals

• eating decomposers

Autotroph means

• the organism can make its own food from photosynthesis

• the organsim gets its energy from eating other organisms

• the organism gets energy from breaking down once living things

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

Carnivores get their energy by

• eating other animals

• eating plants

• eating both plants and animals

• breaking down once living organisms
