Explanation:

🆕 New Concept Discovered: Population Estimation Methods
Estimating population sizes using different sampling techniques.

Step 1: Understand the Methods

• Mark and Recapture: Used primarily for mobile organisms (like fish, birds, or mammals). Researchers capture a sample of animals, mark them, release them, and then capture another sample later to see how many are marked.
• Sampling (e.g., Quadrat Sampling): Used primarily for stationary or slow-moving organisms (like plants, trees, or barnacles). Researchers count individuals within a measured area (quadrat) and extrapolate the density to the entire area.

Step 2: Evaluate the Statement

The statement claims that mark and recapture is always more effective than the sampling method.

This is incorrect because the effectiveness of each method depends entirely on the type of organism being studied:

• For immobile organisms like plants, mark and recapture is highly impractical and ineffective, whereas quadrat sampling is highly effective.
• Therefore, neither method is "always" more effective than the other.
