Understanding Populations Environmental Science

which statement sounds accurate based on the graph data. 

• The zebra and lions do not affect each other
• when lions population increases, so does the zebra population
• When the zebra population increases, it causes the lion population to also increase
• when zebra populations go down, the zebra population goes up.

If the number of births in a population is the same as the number of deaths in a population, what will happen to the growth of the population?

• It will increase.
• It will decrease.
• It will stay the same.
• It will fluctuate.

If you are counting the number of deer in a 10 acre area of hunting land in Washara county, you are measuring the

• density

• population

• distribution

• growth

Number of deaths each year per 1,000 people

• population growth

• population density

• birth rate

• death rate

Number of births each year per 1,000 people

• birth rate

• population growth

• population density

• migration

What type of distribution pattern is evenly spaced apart from one another?

• Uniform

• Clumped

• Random

• Uneven

This is the most commonly seen distribution pattern. Example: wolves. This is usually because there are resources found in particular areas and the organisms need more space to survive.
