population growth

Question 1

geometric pop. growth

Answer 1

modeled geometrically when generations don’t overlap

Question 2

pop. growth rate equals to:

Answer 2

geometric rate of increase

Question 3

exponential pop. growth represents:

Answer 3

pops. w overlapping generations. continuous reproduction.

Question 4

what do exponential growth models show?

Answer 4

pop. growth as continuous

Question 5

when do pops. at exponential rates happen?

Answer 5

favorable environments w abundant resources. low initial pop. densities.

Question 6

where are exponential pops. seen?

Answer 6

colonizing new habitats. exploiting favorable conditions. recovering from stress.

Question 7

when is logistic pop. growth used?

Answer 7

env. limitation. resources depleted, pop. growth rate slows to stop.

Question 8

limiting growth: density-dependent (DD) factors

Answer 8

dependent on pop. size. resource competition, disease.

Question 9

limiting growth: density-independent (DID) factors

Answer 9

independent of pop. size. natural disasters, disturbance.
