Population Growth 2
100
The study of the factors that influence changes in a population’s size
What is population dynamics?
100
The pattern of spacing within an area
What is spatial distribution?
100
Environmental factor that does not depend on population size, such as storms, flood, fires, or pollution.
What is density-independent factor?
100
how fast a specific population grows.
What is population growth rate (PGR)?
100
The number of deaths that occur in the population during a given time period
What is death rate?
200
The number of organisms per unit of living area
What is population density?
200
One of the primary factors in the pattern of dispersion for all organisms
What is food or water?
200
Environmental factor, such as disease, predators, or lack of food, that increasingly affects a population as the population’s size increases.
What is density-dependent factor?
200
movement of individuals away from a population.
What is emigration?
200
A model used to illustrate the number of individuals of a species that survive at any given age
What is survivorship curve?
300
The arrangement of a population in its environment.
What is dispersion?
300
Three types of population dispersion
What are are Uniform dispersion, Clumped dispersion, and Random dispersion.
300
place limits on a population; do not usually kill their hosts, but do take its energy resources and prevent reproduction of a normal number of offspring or reproducing at all; may also prevent the host from competing for other resources
What are parasites?
300
movement of individuals into a population.
What is immigration?
300
Organism tends to live until the end of a typical life span, the shape of the cure is constant until the end.
What is Type I Survivorship?
400
Distribution where a species can be found throughout its lifetime
What is population range?
400
Spatial distribution of C
What is clumped?
400
as predators increase, prey decreases and vice-versa, as predators decrease, prey increase
What is predation?
400
The number of individuals born in a given time period
What is birth rate?
400
Organisms that often die early in life, the sharp decrease is found at the beginning of the curve
What is Type III survivorship?
500
What is the word Mary Poppins sings?
What is supercalifragilisticexpialidocious ?
500
Spatial distribution of B
What is random?
500
Outbreaks tend to occur when population size has increased and population density is high, making transmission easier
What is disease?
500
In any population, the number of individuals in their pre-reproductive, reproductive, and post-reproductive years.
What is age structure?
500
Organisms are likely to die at any point in life, the shape of the line is consistent
What is Type II Survivorship?
