Overpopulation Flashcards
Limiting factors that affect populations that are used by affects created by increased population
Density dependent
The process used to determine a population of a group of organisms that are mobile and harder to track
Mark recapture
The dramatic increase in a populations total over a short period of time
Exponential
The process used to determine the population of a group of organisms that are easily identified and located
Census
Another term for exponential growth
R selective
The amount of food energy available on the planet
Net primary productivity
Maximum number of organisms that an ecosystem can indefinitely support
Carrying capacity
The study of how organisms interact with their environment
Ecology
Things such as Illness lack of space competition lack of food and pollution that cause populations to be reduced
Limiting factors
The type of dispersion in which organisms are spread evenly through an ecosystem
Uniform
The limiting factors that are not caused by population increases
Density independent
The total number of one species in an area of an ecosystem
Population
The type of dispersion and which groups of organisms are grouped together closely
Clumped
The term used to describe the effect that organisms and people have on their ecosystem that is determined by how many resources they use
Ecological footprint
The birthrate minus the death rate of a group of organisms
Growth rate
The term for the rise in a population even though the growth rate is decreasing
Demographic momentum
The name for substances that cannot be re-created after they are used up
Nonrenewable resources
The process of birthrates gradually decreasing it to match Loring a death rates
Demographic transition
Another term for caring capacity with in a population
K selective
The type of dispersion in which there is no definite pattern or growth of organisms in an ecosystem
Random
Shows individuals that have a high probability of surviving through early and middle life but a rapid decline into surviving later life
Type one survivorship curve
Roughly constant mortality rate for the species through its entire life
Type to survivorship curve
Few individuals will live into adulthood and die as they get older
Type III survivorship curve
Three limiting factors in an ecosystem
Whether food source space
