Answer:
Option A 400 individuals
Explanation:
Using this formula, we can estimate the population size of the canvas backs as this is a capture-recapture method.
N = (MxC) / R
Where N = estimated Number of individuals in the population
M = number of individuals captured and Marked = 200
C = total number Captured the second time (with and without a mark) = 200 and
R= number of individuals Recaptured (those with a mark) = 100
Thus, we have
N = (MxC) / R
= (200 x 200) / 100
= (40,000) / 100
= 400 individuals.
