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: C
Explanation
The formula for estimated population is \(\frac{No of marked in 1st capture}{No of species} = \frac{No of marked in 2nd capture}{no of species in 2nd capture}\) = \(\frac{200 \times 120}{40} = 600\)
