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) =Birth - Death/N
2: In a “stable” population, the growth rate: will stay the same ___________________
3: What does “d” mean in this equation?
-The d means the change in the N or T
4: How could you easily find the value of an exponential growth curve?
-You can use the excel and growth rate of the animals and see the increase
5: Why is exponential growth also called a “J-shaped” curve?
-Because it is always quickly increasing
6: What is the algebraic solution to exponential growth? Write the equation and define each.
-N(t)=N(1+r)^t
n: population size
t: is time
r: growth rate
7: In exponential growth, “Is the sky the limit?”
-No, because r does not stay the same forever it changes
What are some of the factors that inhibit population growth?
-food
-shelter
-resources
