Suppose that poaching reduces the population of an endangered animal by 5% per year. Further suppose that when the population of this animal falls below 30 , its extinction is inevitable (owing to the lack of reproductive options without severe in-breeding). If the current population of the animal is 1300, when will it face extinction? Comment on the validity of this exponential model. It will take about ___?___ years for the animal to face extinction.
(Do not round until the final answer. Then round to the nearest whole number as needed.)
Comment on the validity of this exponential model.
The model is ___?__ because the initial population is ___? and at this rate of decaying, the number of years predicted by the model is __? for the population to face extinction due to the lack of reproductive options.
