Web60 seconds. Q. Clive wants to estimate the number of bees in a beehive. Clive catches 50 bees from the beehive. He marks each bee with a dye. He then lets the bees go. The next day, Clive catches 40 bees from the beehive. 8 of these bees have been marked with the dye. (i) Work out an estimate for the number of bees in the beehive. notwhyMark and recapture is a method commonly used in ecology to estimate an animal population's size where it is impractical to count every individual. A portion of the population is captured, marked, and released. Later, another portion will be captured and the number of marked individuals within the … Meer weergeven Typically a researcher visits a study area and uses traps to capture a group of individuals alive.
