For which population of animals is mark-and-recapture the most appropriate method for measuring its population size?
- humans
- large aquatic animals, such as whales
- sea stars
- very small animals, like honeybees
In the mark-and-recapture method, the proportion of marked to captured animals can be used to estimate the entire population size.

What is the difference between population size and population density?
- Size is expressed as animals per unit of area.
- Density is expressed as animals per unit of area.
- Size is always an accurate count of every individual.
- Density is always an accurate count of every individual.
The density of a population is its size divided by the area it inhabits.
The density of a population is its size divided by the area it inhabits.
The density of a population is its size divided by the area it inhabits.
The density of a population is its size divided by the area it inhabits.
If there are 10 squirrels in a 1 km2 area, what is the population density?
- 10 squirrels
- 100 squirrels
- 1 squirrel/km2
- 10 squirrel/km2
Density is calculated as the number of individuals divided by their inhabited area.
Density is calculated as the number of individuals divided by their inhabited area.
Density is calculated as the number of individuals divided by their inhabited area.
Density is calculated as the number of individuals divided by their inhabited area.
What will be the distribution pattern of a population of fish that live in schools?
- evenly dispersed
- randomly dispersed
- clumped
- unclumped
Animals that are behaviorally dependent on one another will be clumped throughout their inhabited area.
Animals that are behaviorally dependent on one another will be clumped throughout their inhabited area.
Animals that are behaviorally dependent on one another will be clumped throughout their inhabited area.
Animals that are behaviorally dependent on one another will be clumped throughout their inhabited area.
Which of the following is a major determinant of the distribution pattern of a population?
- the exact age of every individual
- genetic diversity
- how long each individual will live
- resource distribution
How individuals within the population interact and the distribution of the resources on which they depend determine how much space there will be between individuals.
How individuals within the population interact and the distribution of the resources on which they depend determine how much space there will be between individuals.
How individuals within the population interact and the distribution of the resources on which they depend determine how much space there will be between individuals.
How individuals within the population interact and the distribution of the resources on which they depend determine how much space there will be between individuals.
What information do we need to create a graph of age distribution?
- number of individuals within each age range
- exact age of every individual
- rate of population growth
- how long each individual will live
Age distribution divides the age of the population into ranges and gives the count of individuals in each range.
Age distribution divides the age of the population into ranges and gives the count of individuals in each range.
