The total number of individuals living in a defined area is called the  ___________ _______.

What is population size?

100

The total collection of alleles in a population is called the _____ _____.

What is the gene pool?

100

Hardy–Weinberg equilibrium occurs when allele frequencies in a population _____ _____.


What is remain constant?


100

An interaction where both species benefit is called this.

What is mutualism?

100

The gradual change in a community over time is known as this.

What is succession?

200

This type of growth occurs when resources are unlimited and produces a J‑shaped curve.

What is exponential growth?

200

A change in allele frequencies within a population over time is known as this.

What is evolution?

200

The equation used to calculate genotype frequencies is this.

Answer: What is p² + 2pq + q² = 1?


200

This interaction benefits one species while harming the other.

What is parasitism?

200

Succession that occurs in an area without soil is called this.

What is primary succession?

300

The maximum population size an environment can support is known as this.

What is carrying capacity?

300

 This random change in allele frequencies is more common in small populations.

What is genetic drift?

300

In Hardy–Weinberg calculations, p represents this.

What is the frequency of the dominant allele?


300

When two species compete for the same limited resource, this occurs.

What is competition?

300

Succession following a disturbance where soil remains is called this.

What is secondary succession?


400

This growth model produces an S‑shaped curve as limiting factors slow population growth.

What is logistic growth?

400

When a small group breaks away and forms a new population, this effect may occur.

What is the founder effect?

400

One condition of Hardy–Weinberg equilibrium is that the population must be this size.

What is very large?

400

A predator–prey relationship often results in this type of population cycle.

What are cyclical population fluctuations?

400

The first species to colonize bare rock are typically these organisms.

What are lichens?

500

Predation, competition, and disease are examples of this type of limiting factor.

What are density‑dependent limiting factors?

500

The movement of individuals into or out of a population results in this genetic effect.

What is gene flow?

500

 If natural selection occurs, allele frequencies will do this.

What is change?

500

 This principle states that two species cannot occupy the same niche indefinitely.

What is the competitive exclusion principle?

500

A stable, mature community at the end of succession is called this.

What is a climax community?
