The mark and recapture method of determining population size is always more effective than the sampling method.

Answer,

The above statement is false.

Explanation,

Mark recapture method is where members of a population are captured and marked then released.Sometime later the sampler comes back and captures  again the members of a population and determines the ratio of the marked and unmarked.The ratio of the marked individual to caught individuals is the approximately equal to ratio of originally marked individuals to the total population.The sampling method involves counting the total number of organisms in a certain area and then using that number to determine the total number of organisms in a larger area.There sampling will be more effective it all organism in a certain area while the mark recapture you might end capturing the same individuals that were initially marked
