Population Density Distribution Diversity

The density of a population is a measure of

• how the indivduals are arranged in the population

• how the indivduals access resources

• how many indivduals are in a given area

• how many individuals in the all of the populations together

A farmer plants an orchard of apple trees. What is the most likely dispersion pattern of that popualtion.

• random

• uniform

• clumped

• scattered

To calculate square area you

• multiply length times length

• multiple length times width

• add length and width

• divide total area by length

The average number of people living in an area

• population distribution
• population density
• urbanization
• population rate

Which of the following best describes a population?

• members of the same species living in the same place at the same time
• all the red birds in an area
• all types of organisms living in the same place
• all members of the same species

Random sampling is often used for

• mobile populations

• populations with a varaible habitat

• populations that do not move

• nocturnal organisms only

Mark and recapture is a sampling protocol best used for

• mobile populations.

• stable populations.

• struggling populations.

• randomly dispersed populations.

Ecologists sample or estimate populations because

• it is way more accurate.

• most are lazy.

• it is traditional

• it is the most cost and time efficient.
