Exponential Growth
1: Write the equation for exponential growth- define each part. (What do you need to know?)
N=Population size, r (growth rate) = (Births-Deaths)/N dN/dt
2: In a “stable” population, the growth rate: Constant
3: What does “d” mean in this equation?
Change in
4: How could you easily find the value of an exponential growth curve?
You can easily find the value of exponential growth curve by entering initial numbers and the value of growth into a formula
5: Why is exponential growth also called a “J-shaped” curve?
Exponential growth is also called a "J-shaped" curve because of its shape
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?
The sky is the limit in exponential growth. Growth can not continue forever, there will always be something that stops further growth or decreases growth. These factors can include food, water, land, and other resources
