Use the information on capture-recapture method to calculate the total number of organisms in a habitat. A. 200 B. 360 C. 600 D. 800 Detailed SolutionThe formula for estimated population is\(\frac{No of marked in 1st capture}{No of species} = \frac{No of marked in 2nd capture}{no of species in 2nd capture}\) = \(\frac{200 \times 120}{40} = 600\) |
