Population

a group of organisms of the same species populating a given area

Community

other

ecosystem

a system formed by the interaction of a community of organisms with their physical environment

biosphere

the regions of the surface and atmosphere of the Earth (or other planet) where living organisms exist

habitat

the type of environment in which an organism or group normally lives or occurs

niche

(ecology) the status of an organism within its environment and community (affecting its survival as a
species)

size

the property resulting from being one of a series of graduated measurements (as of clothing)

population density

number of individuals per unit area

dispersion

The pattern of distribution of organisms in a population

age structure

proportion of people in different age groups in a population

survivorship curves

They show the likelihood of survival at different ages throughout the lifetime of the organism.

type I

, Survivorship curve in which the likelihood of dying is small until late in life, when mortality increases
rapidly (such as Humans or elephants).

type II

Survivorship curve in which there is an equal likelihood of dying throughout life (such as birds or small
mammals).

type III

Survivorship curve in which organisms are most likely to die when young; the few survivors tend to live
until old age (such as oysters, salmon, or insects).

biotic potential

the maximum reproductive rate of an organism, given unlimited resources and ideal environmental
conditions

carrying capacity

largest number of individuals of a population that a environment can support

limiting factors

Conditions in the environment that put limits on where an organism can live

density-dependent factors

limiting factors (such as competition, predation, parasitism, and disease) that are affected by the number
of individuals in a given area

density-independent factors

limiting factor that affects all populations in similar ways, regardless of population size

reproductive rate

R= (births-deaths)/N [N- population size at beginning of interval]

growth rate

the amount by which a population's size changes in a given time

intrinsic rate

the mean rate of growth of a population calculated by birth minus death rates when the population is
free of competition with other species and from other factors that affect growth.

exponential growth

growth pattern in which the individuals in a population reproduce at a constant rate

logistic growth
