ObjectivesWe are learning to…

explain how birth, death, immigration, and emigration influence population size

We will be successful when we can…explain how populations grow using both exponential and logistic growth patterns

What Limits Population Growth?

DD or DI?

a. Rainbow smelt and yellow perch attempt to occupy the same area. The more aggressive smelt survive; the perch do not. DD - competition between species only occurs at certain densities

DD or DI?

b. A severe flood brings a lot of sediment and silt into Lake Winnipeg. The turbidity of the lake increases greatly.

DI - natural disasters affect all populations regardless of density

DD or DI?

c. A drought decreases the water level in Lake Winnipeg. The carrying capacity of the lake decreases. DI - natural disasters affect all populations regardless of density

DD or DI?

d. Due to the introduction of rainbow smelt, Lake Winnipeg becomes crowded and some fish species do not survive. DD - crowding only occurs at certain densities

DD or DI?

e. Since northern pike prey on yellow perch, an increase in the perch population causes an increase in the pike population. DD - predation only occurs at certain densities

DD or DI?

f. Many fish die due to an increase in water temperature. DI - temperature affects all population densities

DD or DI?

g. Due to over-fishing, the number of walleye in Lake Winnipeg decreases. DI - human activities affect all population densities

DD or DI?

h. A population is growing quickly when parasites cause disease to spread quickly. DD - parasitism only affects certain population densities

DD or DI?

i. Since lake sturgeon migrate long distances to spawn, many do not survive the trip. DI - behaviors of organisms affect all population densities
