Bio

all of the biotic and abiotic factors in the are where an organism lives

composed of all of the physical, chemical, and biological factors that a species needs to stay healthy or reproduce

two species are competing for the same resources

species that occupy similar niches but live in different geographical regions

occurs when two organisms fight for the same limited resources

the process by which one organism captures and feeds upon another organism

a close, ecological relationship between two or more organisms of different species

an interspecies interaction in which both organisms benefit from another

a relationship between two organisms in which one recieves an ecological

a relationship similar to predation in that one organism benefits while the other is harmed

a measurement of the number of individuals living in a defined space

the way in which individuals of a population are spread in an area or volume

generalized diagram showing the number of surviving members over time from a measured set of births

the movement of individuals into a population from another person

the movement of individuals out of a populations and into another

occurs when a population size increases dramatically over a period of time

a population begins with a period of slow growth followed before leaving off at a stable size

the maximum number of individuals of a particular species that the environment can normally and consistently support

a dramatic decline in the size of a population over a short period of time

the factor that has the greatest effect in keeping down the size of a population

limiting factors that are affected by the number of individuals in a given area

the aspects of the environment that limit a population's growth regardless of the density of the population

the sequence of biotic changes that regenerate a damaged community or create a community in a previously uninhabited area

establishment and development of an ecosystem

the first organisms that lived in previously uninhabited area
