Question

to calculate the results of a tag and recapture sampling, what does a researcher need to identify? the ratio of averaged captures to averaged tags over a period of multiple trials the percentage of the species that was not captured in the sampling process the percentage of only the individuals that were recaptured from the sample the exact species being studied along with everything they eat

Explanation:

Step1: Tag and recapture principle

Tag and recapture uses ratios from multiple trials.

Step2: Analyze each option

• Option 1: Ratio from multiple trials is key.
• Option 2: Uncaptured percentage not main focus.
• Option 3: Only recaptured individuals’ percentage is limited.
• Option 4: Species and diet not relevant to calculation.

Answer:

the ratio of averaged captures to averaged tags over a period of multiple trials
