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 ...

The capture-recapture method is used to estimate the total population size of a species in a given area. The formula for this method is: Total population size = (number marked in first sample * number in second sample) / number marked in second sample Using the values given in the question: Number marked in first sample = 200 Number in second sample = 120 Number marked in second sample = 40 Plugging in these values into the formula, we get: Total population size = (200 * 120) / 40 = 600 Therefore, the total number of organisms in the habitat is 600. So the answer is option C - 600.
