Includes all of the living and nonliving components of the environment in which an organism lives.
What is habitat?
100
Occurs when two organisms fight for the same limited resource.
What is competition?
100
The measurement of the number of individuals living in a defined space or area.
What is population density?
100
This term describes the maximum number of individuals of a particular species that the environment can support.
What is carrying capacity?
100
A sequence of changes that recreate a damaged community in an area completely destroyed by a natural disaster.
What is primary succession?
200
Part of the environment that a species uses to survive and reproduce.
What is ecological niche.
200
Occurs when one organism captures and feeds upon another organism.
What is predation?
200
The way in which individuals of a population are distributed or spread out in an area.
What is population dispersion?
200
A large decrease in the size of a population over a short period.
What is a population crash?
200
RIDDLE TIME: What animals can jump higher than a building?
What is: "All animals can jump higher than a building. Buildings cannot jump"?
300
Results when two species are competing for the same resources, and one species is better suited while the other is pushed out of that niche (or goes extinct).
What is competitive exclusion?
300
Close ecological relationship between two or more organisms of different species.
What is symbiosis?
300
These are the three types of population dispersion.
What is Clumped dispersion, Uniform dispersion, and Random dispersion?
300
This factor limits population growth regardless of the population size, and includes unusual weather, natural disasters, and human development of the environment.
What is a density-independent limiting factor?
300
The first organisms to move into an area.
What is a pioneer species?
400
Two species may live in a similar ___________ but occupy a different _____________
What is habitat and niche?
400
This type of symbiosis is when one species benefits and the other is neither helped nor harmed, such as the squirrel making a nest in a tree.
What is commensalism?
400
This diagram shows the number of surviving members over time for measured number of births.
What is a survivorship curve?
400
These two factors increase the size of a population.
What is immigration and births?
400
The regrowth of a damaged ecosystem in an area that still has healthy soil.
What is secondary succession?
500
This term describes organisms that occupy a similar niche but are in different geological locations.
What is ecological equivalent?
500
Describe how a deer is considered a predator.
What is it captures and feeds upon grass and other plants?
500
This survivorship curve, of humans and other mammals, describes a low level of infant mortality and a species that typically lives to old age.
What is a type 1 survivorship curve?
500
These 4 factors limit a population size more as the population becomes larger. They are density-dependent limiting factors. Name 3 and get the points.
What are competition, predation, parasites, and disease?
500
