Succession
Populations 1
Population 2
100
the general place where an organism lives
Habitat
100
Any necessity of life
Resource
100
THIS type of succession begins on bare rock
Primary succession
100
the number of individuals per unit area.
population density
100
a factor that controls the growth of a population
limiting factor
200
How an organism lives within its habitat
niche
200
An interaction in which an animal feeds on plants
Hervibory
200
THIS type of succession can occur relatively quickly
Secondary succession
200
the size of the area inhabited by a population
geographic range
200
when individuals move OUT of a population’s range
emigration
300
limiting factors that affect all populations in similar ways, regardless of the population density
density independent
300
A symbiotic relationship in which one organism benefits and the other is neither harmed or helped (SPELLING COUNTS!)
commensalism
300
This would most likely occur after a forest fire
Secondary Succession
300

how individuals in a population are spaced out across their range (there are  3 types)

Population dispersion

300
A decline of a predator population would result in THIS of its prey population
increase
400
occurs when organisms try to use the same limited ecological resource in the same place at the same time
competition
400

When 2 species compete for the same resource, they sometimes divide this resource. This is an example of 

Niche Partitioning

400
These are the first organisms to repopulate an area affected by a volcanic eruption
Pioneer species
400
2 factors that cause populations to increase in size
births & immigration
400
maximum number of individuals of a species that an environment can consistently support.
carrying capacity
500
species that occupy similar niches, but in different geographic regions
ecological equivalents
500
No two species can occupy the same niche in the same habitat at the same time because of THIS
Competitive Exclusion Principle
500
Lichen growing on rocks is an example of THIS type of succession
Primary succession
500
When the canine parvovirus (CPV) killed the majority of wolves on Isle Royale in 1980, what type of limiting factor was at work?
Density Dependent
500
when a population’s growth slows and then stops, following a period of exponential growth
logistic growth
