Populations (ES)

When a member moves into a population it is called

• emigration.
• immigration.
• birth rate.

The largest population an area can support is known as

• a limiting factor.
• the death rate.
• carrying capacity.
• exponential growth

Resources such as food, water and available space would be considered limiting factors.

• true
• false

If the birth and immigration rates are greater than the death and emigration rates...

• the population will increase.
• the population will decrease.
• the population will remain the same.
• the population will no longer exist.

Two new squirrels join an existing population of about 100 squirrels. This would be an example of

• emigration.
• immigration.
• having a fight with your squirrel parents.
• logistic growth

When looking at a line graph, you can tell when a population reaches carrying capacity by seeing

• when the growth begins to decline.
• when the growth begins to level off.
• when the growth begins to rise steadily.
• when there is no change in growth.
