Question
A population of fish has 11,140 individuals. They have a death rate of 100 per year and a birth rate of 120 per year. Assuming 50 fish migrate into the population and 25 migrate out of the population per year, how many individuals would there be after the first year? (To answer, write numerals in the box below.) Fill in the blank
Solution
To calculate the number of individuals after the first year, we need to consider the initial population, the death rate, the birth rate, and the migration rate.
Step 1: Start with the initial population of 11,140 fish.
Step 2: Subtract the number of fish that die each year. 11,140 - 100 = 11,040 fish.
Step 3: Add the number of fish that are born each year. 11,040 + 120 = 11,160 fish.
Step 4: Add the number of fish that migrate into the population each year. 11,160 + 50 = 11,210 fish.
Step 5: Subtract the number of fish that migrate out of the population each year. 11,210 - 25 = 11,185 fish.
So, after the first year, there would be 11,185 individuals in the population.
