100
Group of organisms, all same species, that lives in a specific area.
What is a population?
100
The number of live births per 1000 Population in a given year.
What is birthrate?
100
The number of individuals moving into an area per unit time.
What is Immigration
100
A density-dependent factor.
What is competition, disease, parasitism, or predation?
100
The pattern of spacing between individuals across the range of a population
What is population distribution?
200
In this growth pattern a period of rapid population growth is followed by a slow in growth and a leveling off of population numbers.
What is logistic growth?
200
Number of death per 1000 population in a given year.
What is Death Rate
200
The number of individuals moving out of an area per unit time.
What is Emigration
200
Factors that affect members of a population equally regardless of population numbers..
What are density-independent factors?
200

This is usually a pioneer species in a primary succession - be specific.

Lichen

300
The number of organisms of one species that an environment can support indefinitely.
What is carrying capacity?
300

Is the technique used to calculate the approximate population size of individual organism.

What is Mark and Recapture technique?

300

Population size changes from high birth rate to low birth rate

What is demographic transition?

300

Reproduce very rapidly and produce many offspring.

What is an r-selected organism?

300

This type of growth models population growth under ideal conditions when resources are unlimited.

What is exponential growth?

400
Limiting factor such as disease, parasites, or food availability that affect growth of a population.
What is a Density-Dependent Factor?
400
Proportions of the population that are different age levels.
What is age structure?

When resources become limited, a population approaches this.
What is carrying capacity?
500
The two ways population numbers can increase
What are by increases in birthrate and immigration?
500
Study of human population size, density and distribution, movement and its birth and death rates.
What is demography?
500
A factor that will limit the size of a population.
What is a limiting factor?
500

Slow rate of reproduction and produce relative few young and care fir then over their lifetime.
