A group of individuals of the same species living within a specified area is a	Population
the number of individuals per unit of area or volume in the habitat is	Population density
Forced by the occurrence of resources, ______ is the most common dispersion pattern in nature.	Clumped
Humans in North America show a ______ distribution pattern.	Clumped
the maximum rate of increase in numbers by a population is	Biotic potential
the factors determining population size	Births, deaths, immigration, and emigration
When births and deaths are equal, there is	ZPG or ‘zero population growth.’
The ‘intrinsic rate of increase (r) is	the difference between the birth rate and death rate
When limiting factors are absent, population growth is	exponential (a ‘J-shaped curve’).
Ideally, populations are limited in size by the habitat	‘carrying capacity (K).’
Carrying capacity (K) is determined by	resource availability and organismal tolerance of habitat conditions.
If population changes are not related to its size, the causative factors are called	‘density-independent.’
For example, a flood that eliminates a population of rabbits would be a _____-_____ event.	‘density-independent’
On the other hand, food supply would be regarded as a ____-____ control on a population.	‘density-dependent’
A weather-related event, such as a drought, would be called a ____-____ control.	‘density-independent’
