How can you Estimate the Population from the Capture-Recapture System?

-Capture a Sample of a Population and Mark them, obviously do not Harm the Animal or Change their Survival Chances. -Release them back, and then Recpature another Sample of the Population - maybe do this in a Day After you Began. -Then, Equation!! Population Size = (Number in First Sample x Number in Second Sample) / Number in Second Sample already Marked. [Keep in Note your Marked Organisms may Die from Natural Causes, so again, this is why its a Prediction. Also Luck is needed - find 0 Organisms marked and well :( ]
