Species with limited resources usually exhibit a....growth curve |
Logistic |
|
The maximum growth rate characteristic of a species is called its |
Biotic potential |
|
The population size of a species capable of being supported by the environment is called its |
Carrying capacity |
|
Species that have many offspring at one time are usually |
r-selected |
|
A forest fire is an example of....regulation |
Density independent |
|
Birth rate |
The number of births within a population at a specific point in time |
|
Carrying capacity |
The maximum number of individuals of a population that can be supported by the limited resources of a habitat |
|
Death rate |
The number of deaths within a population at a specific point in time |
|
Density-dependent regulation |
The regulation of population in which birth and death rates are dependent on population size |
|
Density-independent regulation |
The regulation of population in which the death rate is independent of the population size |
|
Exponential growth |
An accelerating growth pattern seen in populations where resources are not limiting |
|
Intrapsecific competition |
The competition among members of the same species |
|
J-shaped growth curve |
The shape of exponential growth curve |
|
K-selected species |
A species suited to stable environments that produce a few, relatively large offspring and provide parental care |
|
Logistic growth |
The leveling off of exponential growth due to limiting resources |
|
r-selected species |
A species suited to changing environments that produce many offspring and provide little or not parental care (fish) |
|
S-shaped growth curve |
The shape of a logistic growth curve |
|
Zero population growth |
The steady population size where birth rates and death rates are equal |
