Population 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.

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.

• Random

• Uniform

• Clumped

• Ueven

Population Growth

• The action of coming to live permanently in a foreign country. (I = Into)

• The increase in the number of people in a population or dispersed group.

How long will it take a population to double if it's growth rate is 3.2%?

• 224 years

• 2,187 years

• 22 years

• 219 years

Answer explanation

The Rule of 70 is an easy way to calculate how long it will take for a quantity growing exponentially to double in size. The formula is simple: 70/percentage growth rate= doubling time in years.

Using the rule of 70, a population growing at 10% would double in

• 7 years

• 10 years

• 15 years

• 17 years
