Conservationists establish that the minimal viable population of a population of tigers in an extensive geographical area is 16. The current population of tigers is 10. What is likely to happen to the population of tigers?
A.
Tigers from adjoining populations will immigrate into the geographical area of this population.
B.
The tiger population will grow to 16 and then become stable, staying around this figure.
C.
The tigers will die out because they will be unable to sustain their population.
D.
The lifespan of the population of tigers will increase because of less comp
The correct answer is C. The tigers will die out because they will be unable to sustain their population.
The minimal viable population is the minimum number of individuals required for a population to survive and maintain genetic diversity in the long term. In this scenario, the minimal viable population for tigers is determined to be 16. Since the current population is only 10, it does not meet the minimum requirement for long-term survival.
Without enough individuals to maintain genetic diversity and withstand environmental pressures, the population is likely to face increased mortality rates, reduced reproductive success, and decreased adaptation to changing conditions. Consequently, the population is more likely to die out rather than grow or stabilize with only 10 individuals.
To determine what is likely to happen to the population of tigers, we need to consider the concept of minimal viable population (MVP), which refers to the minimum number of individuals required for a population to persist in the long term. In this case, the MVP for the population of tigers is established as 16.
Given that the current population of tigers is 10, we can assess the potential outcomes based on the options provided:
A. Tigers from adjoining populations will immigrate into the geographical area of this population.
If the geographical area has adjoining populations of tigers, there is a possibility that some individuals may migrate into the area, which could increase the population and potentially help reach or maintain the MVP of 16. This option suggests a potential increase in the tiger population.
B. The tiger population will grow to 16 and then become stable, staying around this figure.
In this scenario, the tiger population is expected to grow gradually until it reaches the MVP of 16, after which it will stabilize and maintain a population around that figure. This depends on factors such as habitat suitability, availability of resources, and successful reproduction. This option suggests a potential increase in the tiger population.
C. The tigers will die out because they will be unable to sustain their population.
If the population remains below the MVP of 16 for an extended period, it is possible that genetic diversity and variations in reproductive success may decrease, making it harder for the population to sustain itself. This option suggests a potential decline and possible extinction of the tiger population.
D. The lifespan of the population of tigers will increase because of less competition.
This option does not directly address the population size or the MVP concept. While reduced competition may have an impact on individual survival or lifespan, it does not necessarily lead to an increase in population size.
Based on these options, the most likely outcome would be A or B, depending on various ecological and environmental factors. It is important for conservation efforts to actively monitor the tiger population, assess habitat suitability, and implement appropriate measures to ensure the preservation and growth of the population.
hi xavier, did you used to go to laurens middle school by any chance
We do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though.
