Use the following 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
200
360
600
800
Correct answer is C
The formula for estimated population is
\(\frac{No of marked in 1st capture}{No of species} = \frac{No of marked in 2nd capture}{no of species in 2nd capture}\)
= \(\frac{200 \times 120}{40} = 600\)
