You want to estimate the number of canvas backs (a type of duck) at the Sacramento Wildlife Refuge. In two days you capture 200
Vsevolod [243]

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.
