, When talking about exponential growth rate, what does "t" stand for? - ANS amount of time
over which a population grows
Why would we need to take the derivative of the growth model equation? - ANS determining
the rate of growth at any point in time
What is Geometric growth model? - ANS Compares population sizes at regular time intervals
What would be a good example for when to use a geometric growth model? - ANS California
quail have a distinct breeding period
What can be said about the data points of an exponential model? - ANS Continuous data
point
What can be said about the data point of a geometric model? - ANS Discrete data points
What is a logistic growth model? - ANS Model the slowing growth of populations at high
densities
What does (1-N/K) represent? - ANS Accounts for a decline in growth rate as the population
approaches its carrying capacity
What is carrying capacity? - ANS the maximum population size that can be supported by the
environment
What does dN/dt represent? - ANS the effect of population size on the rate of increase of the
population
