The total number of individuals living in a defined area is called the ___________ _______.
What is population size?
The total collection of alleles in a population is called the _____ _____.
What is the gene pool?
Hardy–Weinberg equilibrium occurs when allele frequencies in a population _____ _____.
What is remain constant?
An interaction where both species benefit is called this.
What is mutualism?
The gradual change in a community over time is known as this.
What is succession?
This type of growth occurs when resources are unlimited and produces a J‑shaped curve.
What is exponential growth?
A change in allele frequencies within a population over time is known as this.
What is evolution?
The equation used to calculate genotype frequencies is this.
Answer: What is p² + 2pq + q² = 1?
This interaction benefits one species while harming the other.
What is parasitism?
Succession that occurs in an area without soil is called this.
What is primary succession?
The maximum population size an environment can support is known as this.
What is carrying capacity?
This random change in allele frequencies is more common in small populations.
What is genetic drift?
In Hardy–Weinberg calculations, p represents this.
What is the frequency of the dominant allele?
When two species compete for the same limited resource, this occurs.
What is competition?
Succession following a disturbance where soil remains is called this.
What is secondary succession?
This growth model produces an S‑shaped curve as limiting factors slow population growth.
What is logistic growth?
When a small group breaks away and forms a new population, this effect may occur.
What is the founder effect?
One condition of Hardy–Weinberg equilibrium is that the population must be this size.
What is very large?
A predator–prey relationship often results in this type of population cycle.
What are cyclical population fluctuations?
The first species to colonize bare rock are typically these organisms.
What are lichens?
Predation, competition, and disease are examples of this type of limiting factor.
What are density‑dependent limiting factors?
The movement of individuals into or out of a population results in this genetic effect.
What is gene flow?
If natural selection occurs, allele frequencies will do this.
What is change?
This principle states that two species cannot occupy the same niche indefinitely.
What is the competitive exclusion principle?
A stable, mature community at the end of succession is called this.
What is a climax community?
