Population Biology

Limiting factors that affect all populations in similar ways, regardless of population size are

• tolerant

• density dependent

• carrying capacity

• density independent

The maximum number of individual organisms that an ecosystem can comfortably support is

• exponential growth

• carrying capacity

• population

• tolerance

J curve - as population gets larger, it also grows faster. This occurs because there are more individuals reproducing as the population grows and is known as

• exponential growth

• logistic growth

• stable growth

• birth rate

Natural and manmade events that slow or stop population growth are

• life history patterns

• population density

• limiting factors

• demographics

The number of individuals of a population in a given area is

• population density

• demography

• slow life history

• age structure

Characteristics of organisms that exhibit a rapid life history pattern

• large species in less stable environments, mature quickly, produce limited offspring and have short life spans

• small organisms, quick maturation, reproduces quickly, many offspring

• small organisms, mature slowly but reproduce quickly, limited number of offspring

• large species in more stable environments, reproduce and mature slowly, produce limited offspring and live relatively long lives

Limiting factor that depends on population size

Ex: competition, predation and herbivory, parasitism and disease, stress from overcrowding

• density dependent

• density independent

• carrying capacity

• tolerance

A population's growth rate is equivalent to

• birth rate + death rate

• birth rate - death rate

• current population - death rate

• current population + birth rate

An age population structure shows

• the number of births within a population

• the number of deaths within a population

• number of males and females of each age in a population

• the growth rate of a population

An organism's pattern of reproduction; may be rapid or slow, is the organism's

• life history pattern

• birth rate

• age population structure

• population density
