Biology Essentials- 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
2: In a “stable” population, the growth rate: _____stays constant______________
3: What does “d” mean in this equation?
d means change
4: How could you easily find the value of an exponential growth curve?
You can easily find the value of exponential growth curve by using a formula to enter numbers into
5: Why is exponential growth also called a “J-shaped” curve?
Because the line goes up exponential making a J-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. Some factors that inhibit population growth are food, water, land, and resources.
