Is the study of how organisms interact with each other and their environments

Is a group of individuals that interbreed and produce fertile offspring biologist recognize, however that this definition can be problematic

Members of a species that live in the same area at the same time make up a population.

All the population in a particular area make up a community

Includes all of the living things and their physical environments within a particular area.

The biosphere includes all parts of Earth that host life, with all of its organisms and its environments.

Parts of an ecosystem that are living or used to be living are called biotic factor.

Parts of and ecosystem that have never been living .

A specific enviorment that an organism lives in is its habitat.

A recource is anything an organism need including nutrients, shelter, breeding sites, and mates.

describes the number of individual organisms in a given population at any given time.

describes the number of individuals within a population per unit area.

Population distribution

sometimes called population dispersion, describes how organisms are arranged within an area.

or age dicrebution describes the relative numbers of organisms of each age within a population.

Age structure diagram

are visual tools scientists use to show their age structure of populations.

a population's sex ratio is it proportion or males to females.

to show how the likelihood of death varies with age ecologist use a graph called survivorship curves.

immigration is the arrival of individuals from outside a given area.

Emigration is the departure of individuals from a given area

migration is the seasonal movement into and out of an area.

when a population increases by a fixed percentage each year, it is said to undergo exponential growth.

are characteristics that limit population growth .

is the largest population size a given enviorment can sustainably support.

logistic growth describes how a population initial exppeirement increase is slowed and finally stopped by limiting factors.

density dependent factor

density dependent factor because its influence changes with population density.

Density-dependent factors

Density-dependent factors are limiting factors whose influence is not affected by population density.

or maximum ability to produce offspring in ideal conditions
