Made up of all the populations of different species that live and interact in an area (ex: all elephants, zebras, birds, grasses, plants, etc.)

a community of organisms and their nonliving environment (abiotic & biotic)(ex: elephants, zebras, birds, grasses, water). This the 1st level to bring in nonliving (abiotic) parts of the environment.

also called a heterotroph - organisms that eat other organisms for their energy

eat only animals

eats plants and animals

obtain energy be eating only plants

break down dead organiz matter (fungi, bacteria, worms)

One organism benefits while the other is harmed (win-lose)

Both benefit (win-win)

One organism benefits while the other is unaffected/doesn't care
