Final answer:
The carrying capacity for deer on the reserve is 5000. None of the options is correct
Step-by-step explanation:
The carrying capacity for deer on the reserve can be defined as the maximum size of the population that can be supported by the available resources. In this case, we can estimate the carrying capacity using the equation N = (M * C) / R, where N is the population size, M is the number of marked deer in the second capture, C is the total number of deer captured in the second capture, and R is the number of marked deer recaptured in the second capture.
From the given information, if 80 deer are captured, tagged, and released into the reserve, and later 100 deer are captured, with 20 of them being already marked, we can apply the equation as follows:
N = (20 * 100) / (20/100) = (20 * 100) / (0.2) = 1000 / 0.2 = 5000
Therefore, the carrying capacity (approximate) for deer on the reserve is 5000.
