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

Producers obtain their energy by

• the process of hunting for prey

• the process of eating plants

• the process of photosynthesis to make their own food from sunlight

• the process of breaking down once living things

The job 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

All living parts of an ecosystem (plants, animals, and decomposers) are depend on one another for

• food

• energy

• cycling matter

Photosysnthesis and respiration are important because

• they make mutualism possible

• they are the building blocks of life

• they are the 6 characteristics of life

• they cycle matter and energy between autotrophs and heterotrophs

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

Herbivores get their energy from

• eating other animals

• eating plants

• using sunlight to make their own food

• breaking down once living things
