grows carrying capacity below births
above under deaths exceed
the number of organisms of one species that an environment can support is called its (16) _. if the number of organisms in a population is (17) _ the environments carrying capacity, if the number of births (18) _ deaths and the population (19) _. if the number of organism rises (20) _ the population capacity of the environment, (21) _ will exceed (22) _. this pattern will continue until the population is once again at or (23) _ the carrying capacity.
match the words to the sentences using the word bank.
age levels rapid fertility proportion stable age structure
24)population growth will change if the largest _ of a population is in its post - reproductive years.
25)the proportions of a population that are at different _ make up its age structure.
26)if you know a population has a large group of individuals in their pre - reproductive years, you would predict that the populations growth will be _.
27)if the proportions of a population at different age levels are fairly equal, the population will be _.
28)the population growth of a country depends on its birth rate death rate, and _ rate.
29)to make predictions about the growth of a population, demographers must know its _.

Explanation:

1. The term for the number of organisms a species an environment can support is carrying capacity.

17 - 23. If population is under carrying capacity and births exceed deaths, it grows; if it exceeds carrying capacity, it will come back to or below it.

1. Population growth changes if the largest proportion is in post - reproductive years.
2. Proportions at different age levels make up age structure.
3. A large pre - reproductive group predicts rapid growth.
4. Equal proportions at different age levels mean a stable population.
5. Population growth depends on birth, death and fertility rates.
6. Demographers need to know age structure to predict population growth.

Answer:

1. carrying capacity
2. under
3. exceed
4. grows
5. above
6. It
7. carrying capacity
8. below
9. proportion
10. age levels
11. rapid
12. stable
13. fertility
14. age structure
