A Population Study: Growth Rate of Walleye Population from 2004 to 2006
Population Growth Analysis
A population of walleye increased from 1200 to 3700 from 2004 to 2006. Let's calculate the growth rate of this population change.
Answer:
The growth rate is 1250 per year.
Explanation:
- First of all, let's consider the population number in both years;
The initial population is 1200 and
Final population is 3700.
- Total increased population is (3700 - 1200) = 2500
So 2500 population were increased in (2006 - 2004) = 2 years.
- To find the annual growth rate: (Increased population / time span in years) = 2500 / 2 = 1250 per year.
- Hence 1250 population was added per year in walleye from 2004 to 2006.
