emigration
The number of individuals of a single species per unit area is known as

limiting population
population density
logistic population
Bacteria employ a(n) _____ reproductive strategy, a characteristic determined by their small size, rapid maturation, and short life span.

A population that grows until it reaches its carrying capacity usually has the shape of an

Density-independent factors are limiting factors whose effects are
confined to the habitat of the population
determined by the degree of competition for resources
not influenced by population densities
determined by the difference between birthrate and population density
For a particular species, the carrying capacity is the maximum number of individual organisms that
the species could reach in a given time period if all the offspring survive and reproduce
could be supported by a given environment indefinitely
are in their post-reproductive years
could be supported by any environment over a period of one year
When you study all the growth characteristics of a human population, you are studying its
reproductive pattern
exponential growth
life-history pattern
demography
Population control factors whose effects increase as the size of the population increases are
abiotic factors
density-dependent factors
limiting factors
density-independent factors
