The maximum population size that can be supported by the available resources of a region is know as ________.
carrying capacity

In Japan, the death rate is higher than the birth rate.
What is happening to the size of the population.
It will decrease.

3 Patterns of Dispersion
Clumped, Uniform, Random

Formula for Population Change
Population Change = (Birthrate + Immigration) - (Deathrate + Emigration)
100
Density
Is the result of an interplay between processes that add individuals to a population and those that remove individuals
200
This word describes individuals leaving a population.
Emigration

2 Types of Limiting Factors
Density-dependent, Density-independent
500
Which would be least likely to be affected by a density dependent factor?
A small scattered population
500
r-Strategist
Characterised by exponential growth, which results in temporarily large populations, followed by sudden crashes in population size
