An area within a coral reef that a clown fish occupies.
What is a habitat
100
If one organism is closely associated with and survives at the expense of another, this type of relationship exists
What is parasitism
100
A type of ecological succession that occurs in an area where there were originally no organisms present and where soil has not yet formed.
What is primary succession
100
This abiotic factor can affect a population size, regardless of the number of organisms in an area. Example: a tornado.
What is a density independent factor
100
Organisms with this life-history pattern have a slow rate of reproduction, produce few young, have a large body size, and live a long time
What is slow life-history pattern
200
The specific role, or way of life, of a species within its environment is.
What is a niche
200
The relationship that exists when one species benefits and the other is neither harmed nor helped
What is commensalism
200
This is the sequence of changes that takes place after an existing community is severely disrupted in some way
What is secondary succession
200
As the number of predators in an ecosystem increases, the number of its prey now decreases. This is an effect of this type of limiting factor.
What is a density dependent factor
200
Organisms with this life-history pattern reproduce very rapidly, have small body size, have many offspring, and are short-lived
What is a rapid life-history pattern
300
Two species cannot occupy this in a community
What is a niche
300
The relationship that exists with both species benefit
What is mutualism
300
Type of succession that takes place when soil already exists
What is secondary succession
300
This is the largest amount of organisms within a population that the existing ecosystem can support.
What is carrying capacity
300
Disease, competition, predators, parasites, and food are these types of limiting factor
What are density-dependent factors
400
This is the ability of an organism to withstand fluctuations in biotic and abiotic environmental factors
What is tolerance
400
A clownfish feeds on small invertebrates that could harm a sea anemone and the anemone's stinging cells protect the clownfish from predators.
What is mutualism
400
These are the first species to take hold in an area during primary succession
What are pioneer species
400
This is a graph that shows exponential growth (starts slowing then increases greatly)
What is a J shaped curve
400
These limiting factors affect all populations no matter how they are dispersed
What are density-independent factors
500
A biotic or abiotic factor that restricts existence, numbers, reproduction, or distribution of an organism is called this
What is a limiting factor
500
Tapeworms attach themselves to the insides of the intestines of animals. They get food by eating the host's partly digested food, depriving the host of nutrients.
What is parasitism
500
A mature, stable community that undergoes very little change
What is a climax community
500
This is the factor that determines population growth of an organism
What is its life-history pattern
500
An example of an organism with a rapid life-history pattern and and an example of an organism with a slow life-history pattern
