Demographic stochasticity refers to random fluctuations in birth and death rates that may lead to variation in population size. In this case, the deviation from the average egg production by some females is an example of demographic stochasticity. Environmental stochasticity refers to random fluctuations in environmental conditions that may affect population size, but this scenario does not involve environmental factors. Damped oscillations and population cycles refer to patterns of population dynamics and are not applicable in this scenario.
