The Limit Does Not Exist
Miscellaneous
100
The seasonal movement of a population from one region to another.
What is migration?
100
A single member of a species.
What is an individual?
100
The survivorship curve when a species has an equal likelihood of death at any age.
What is a Type II ?
100
Water and mates are examples of this type of limiting factor.
What is a density dependent factor?
100
Mufasa from The Lion King is an example of this level of organization.
What is an individual?
200
The number of organisms per square kilometer. For example, 14 lions per 100 square kilometers.
What is population density?
200
All of the living things on Earth and the non-living things with which they interact.
What is the Biosphere?
200
In order for a population to increase if no emigration or immigration is taking place, either death rate must decrease, or this must increase.
What is birth rate?
200
This is determined by the limiting factors of the population.
What is the carrying capacity?
200
The amount of time that it takes to grow offspring and to get to reproductive age, when combined, are known as this.
What is biotic potential?
300
When organisms leave a population.
What is emigration?
300
A group of organisms of the same species in an area.
What is a population?
300
This growth pattern has a J shaped curve on a graph.
What is exponential growth?
300
Disease is an example of this type of limiting factor.
What is a density dependent factor?
300
Wolves are territorial species, so they are often distributed in this pattern.
What is uniform distribution?
400
When a large discrepancy exists between the number of males and females. For example, when there are 20 females and 80 males in a population.
What is an uneven sex ratio?
400
A collection of populations of different species in an area.
What is a community?
400
When a population has stopped growing at a constant rate and begins to level off.
What is logistic growth?
400
Flooding is an example of this type of limiting factor.
What is a density independent limiting factor?
400
The way in which ecologist often collect data on population numbers, since counting each individual is quite challenging.
What is a random sample?
500
Biotic or abiotic factors that are necessary for the survival of a species.
What are resources?
500
A community and all of the non-living things with which it interacts.
What is an ecosystem?
500
This is the equation for population growth rate.
What is (birth rate + immigration) - (death rate + emigration)?
500
This takes place after a population overshoots its carrying capacity temporarily.
What is a population crash?
500
A population starts with 120 individuals and contains 132 individuals the following year. It has increased by this much.
