Answer 4

meta-populations

Question 5

In what 2 ways are meta-populations examined?

Answer 5

Answer 6

birth rates and survival rates are constant overtime

Question 7

What is stable age distribution?

Answer 7

age structure does not change from one year to the next

Question 8

Answer 8

age structure

Question 9

What happens when a lot of individuals in a population are young?

Answer 9

population grows

Question 10

What happens when a large number of the population is past reproductive age?

Answer 10

population declines
