Assignment 1 Grading Criteria
|
|
|
Select a population size (population could consist of people, animals, microorganisms, or plants).
|
20
|
|
Select a positive annual percent growth rate per year, which should be greater than 0%.
|
20
|
|
Calculate what the future size of the population will be, given the below assumptions.
Use the exponential equation:
•
Future value = Present value *exp(rt)
•
Where exp is the base “e” of exponential,
•
r = annual rate of growth, expressed as a percent
|
20
|
|
Repeat the calculation for SECOND value of t (make sure they are at least two years apart from one another).
|
20
|
|
Repeat the calculation for THIRD value of t (make sure they are at least two years apart from one another).
|
20
|
|
Graph the results for population growth by % growth rate, vs. time in years for all FIRST calculations of t.
|
40
|
|
Graph the results for population growth by % growth rate, vs. time in years for all SECOND calculations of t.
|
40
|
|
Graph the results for population growth by % growth rate, vs. time in years for all THIRD calculations of t.

|
Explain the implications of this growth rate for the population’s resource use and the environment.
|
40
|
|
Explain the likelihood of your above results.
Would it be expected that the % growth rate would stay constant over long periods?
