Succession
Populations 1
Population 2
100
the general place where an organism lives
Habitat
100

define commensalism and give an example

when one organism benefits and one is not affected

100
THIS type of succession begins on bare rock
Primary succession
100

the number of individuals per unit area.

population density 100 extra points to state how you calculate population density

100

What is a resource in ecology

food, space, shelter, mates

200
How an organism lives within its habitat
niche
200

What is it called when 2 organisms of different species fight for a resource?

Interspecific

200
THIS type of succession can occur relatively quickly
Secondary succession
200

4 characteristics of a population (test question)

Geographic Distribution, Population Density, Growth rate, age structure.

200

when individuals move in of a population’s range

immigration

300
limiting factors that affect all populations in similar ways, regardless of the population density
density independent
300

A symbiotic relationship in which both organisms benefits.

mutualism

300

What is ecological succession

the process by which the mix of species and habitat in an area changes over time.

300

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

Population dispersion clumped, random,uniform

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

What is it called when two of the same species compete for a resource

Intraspecific

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
What is the difference between density dependent and density independent

Density Dependent depends on how many organisms in an area and density does not depend on the population size. 

500

when a population’s growth that occurs when there is an abundant amount of resources

exponential growth
