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)
