Geometric growth model
Classify each statement according to whether it applies to the
exponential or geometric growth model:
assumes growth at specific intervals over a period of time Ans:

Therefore, the annual growth rate (λ) of the population equals
_______. Ans: When the intrinsic growth rate (r) of a population
equals zero, the population size after one year (N1) is EQUAL TO
the initial population size (N0).
Therefore, the annual growth rate (λ) of the population equals 1.
Select the population growth model for a small group of white-
tailed deer, which give birth each spring.
-exponential growth
-linear growth
-logistic growth
-geometric growth Ans: Geometric growth
Why is the selected model of population growth appropriate for
white-tailed deer?
-It models species that reproduce at discrete intervals.
-It models species that reproduce at very slow rates.
-It models species that reproduce continuously.
-It models species that have strict limits to their population sizes.
Ans: -It models species that reproduce at discrete intervals.
