Exponential Growth
Biology Essentials-
Exponential
Growth
Name: ____________________________________
1: Write the equation for exponential growth- define each part. (What do you need to know?)
N- Population size
r= growth rate
R= births-death/N
2: In a “stable” population, the growth rate stays the same
3: What does “d” mean in this equation?
d means change in the equation
4: How could you easily find the value of an exponential growth curve?
To find the curve easily you can use excel spreed sheet.
5: Why is exponential growth also called a “J-shaped”
curve?
Because the line looks like a curve just like the letter "J"
6: What is the algebraic solution to exponential growth? Write the equation and define each.
N(t)=N(1+r)^t
N= population size
R=growth rate
t= time
7: In exponential growth,“Is the sky the limit?”What are some of the factors that inhibit population growth?
food, resources and space.
