Use the information on capture-recapture method to calculate the total number of organisms in a habitat.
First capture = 200
Second capture = 120
Number of organisms with mark in second capture = 40

The total number of organisms therefore is

  • A.
    200
  • B.
    360
  • C.
    600
  • D.
    800
Correct Answer: Option C
Explanation

The formula for estimated population is

(frac{No of marked in 1st capture}{No of species} = frac{No of marked in 2nd capture}{no of species in 2nd capture})

= (frac{200 times 120}{40} = 600)
