population |
consists of all individuals of a species that live together in one place, at one time |
|
|
population density |
number of individuals that live in a given area |
|
|
population model |
hypothetical population that attempts to exhibit the key characteristics of a real population |
|
|
carrying capacity |
the population size that an environment can sustain |
|
|
logistic model |
population model in which exponential growth is limited by a density-dependent factor |
|
|
r-strategist |
grow exponentially when environmental conditions allow them to reproduce |
|
|
population size |
the numbers of individuals in a population |
|
|
dispersion |
the way the individuals of population are placed |
|
|
exponential growth curve |
the rate of population growth, stays the same. as a result the population size increases steadily |
|
|
density dependent factor |
the rate at which they become depleted depends upon the population density of the population that uses them |
|
|
density independent factor |
growth that is limited not by environmental conditions |
|
|
k-strategist |
population density is usually near the carrying capacity |
