Community All the different populations that live together in an area.
Ecosystem The community os organisms that live in a particular area, along with their nonliving environment.
Ecology The study of how organisms interact with each other and there environments.
Immigration Moving into a population

Limiting Factor An environmental factor that causes a population to stop growing or decrease in size (ex. weather conditions, space, food, and water)
Carrying Capacity The largest population that an area can support.
Niche The role of an organism in its habitat.
Competition The struggle between organisms to survive as they attempt to use same limited resources.
Symbiosis A relationship in which two species live closely together and at least one of the species benefits.
Mutualism A relationship in which both species benefits.
Commensalism A relationship in which one species benefits and the other species is neither helped nor harmed.
Parasitism A relationship that involves one organisms living with, on, or inside an organism and harming it.
Species - Sentence Scientists are still finding new SPECIES of animals today.
population - Sentence When animals get hit by cars it decreases the POPULATION of the species in that area.
Ecosystem - Sentence ECOSYSTEMS are mostly in forests or wide ranges of land.
Ecology - Sentence Im thinking about studying ECOLOGY for my science project this year.
Immigration - Sentence When the days get colder the animals know its IMMIGRATION season.
Emigration - Sentence EMIGRATION is when an organism wants to leave the "community" to move to another.
Population Density - Sentence The POPULATION DENSITY determines the amount of organisms in that area.
Limiting Factor - Sentence When weather conditions are bad and other problems are repeatedly going on in the community the organism might refer to a LIMITING FACTOR.
Carrying Capacity - Sentence The CARRYING CAPACITY determines the amount of people or organisms you can have in that area.
Niche - Sentence Each group of organisms has a NICHE in its habitat.
Competition - Sentence The animals were having a COMPETITION to see who could get to the food the fastest.
Symbiosis - Sentence Fish and reefs have a good SYMBIOSIS.
Mutualism - Sentence Flowers and bees have perfect MUTUALISM.
Commensalism - Sentence Birds hanging out on cows backs is a great example of COMMENSALISM.
Parasitism - Sentence The owl benefits from the chipmunk by eating it so they have a PARASITISM.
