2.2 Study guide

Question 1

How is population growth determined?

Answer 1

Population growth is determined by the limiting factors or a formula is dN/dt=rN(K-N/K)

Question 2

How do you sketch a basic graph for exponential growth?

Answer 2

You find the rate of growth by dN/dt=rN. Then you apply the rate of growth to N and graph it

Question 3

How do you sketch a basic graph for logistic growth?

Answer 3

You find the carrying capacity of the environment. Then you find the rate of growth by using the formula dN/dt=rN(K-N/K) and apply it to the graph.

Question 4

What are the variables?

Answer 4

N=Pop. size
t=Time
dN/dt=Pop. growth rate
r=Max per capita growth rate
N0=initial pop. size
