| carrying capacity | the number of organisms of one species that an ecosystem can support |
| niche | a species role in an ecosystem |
| producer | all food chains begin with producers; they are autotrophs; largest section of ecology pyramid |
| autotrophs | can make their own food HINT: auto = self |

| herbivore | feeds on plants |
| carnivore | feeds on animals |
| omivore | feeds on both plants and animals |
| scavenger | eats dead organisms |
| parasites | feeds off living organisms |
| decomposers | recycle materials; all food chains end with decomposers; smallest section of ecology pyramid ex. bacteria, fungus |
| energy | only 10% is passed on to the next higher level; 90% is lost to reactions and heat |
| biodiversity | the variety of species in an area; greater the biodiversity, the greater the stability; lost by rainforest clearing, agriculture, over hunting |
