Early this spring researchers have recently discovered that there is one small remnant population of endangered bluegrass left in a small prairie plot outside of Kansas City. If there are approximately 850 individuals in the cohort, how many individuals can the researchers expect to find alive at the end of the summer, 6 months later?

Question

Early this spring researchers have recently discovered that there is one small remnant population of endangered bluegrass left in a small prairie plot outside of Kansas City. If there are approximately 850 individuals in the cohort, how many individuals can the researchers expect to find alive at the end of the summer, 6 months later?

a. Approximately 1000

b. Approximately 330

c. Approximately 700

d. Approximately 45

e. None of the individuals will be alive 6 months later.
help please

Answer 1

c. Approximately 700

Answer 2

To determine the number of individuals the researchers can expect to find alive at the end of the summer, we need to consider the reproductive capacity and survival rates of the bluegrass population.

First, let's clarify that the growth rate of bluegrass and its survival in the given environment can vary. However, for the purpose of this explanation, let's assume a moderate growth rate and assume that the population follows basic principles of population biology.

To estimate the population size after six months, we need to consider births, deaths, and immigration/emigration rates. Since it is mentioned that the bluegrass population is endangered, we can assume that immigration and emigration rates are negligible, meaning that there is no significant migration of individuals into or out of the population.

The reproductive capacity of bluegrass depends on factors like individual fertility and environmental conditions. As an approximation, let's assume that each individual can produce an average of 2 offspring during the spring to summer season.

So, if there are 850 individuals at the start of spring, and each individual produces 2 offspring, we can estimate that by the end of the summer, there would be an additional 850 * 2 = 1700 offspring.

Considering both the surviving adults and the newborn offspring, the total number of individuals at the end of the summer would be 850 (original adults) + 1700 (offspring) = 2550.

Therefore, the researchers can expect to find approximately 2550 individuals alive at the end of the summer. Since this option is not among the given answer choices, it seems like there might be a mistake in the question or answer options.

If you believe none of the given answer options are correct, you should check the question and answer choices again for any discrepancies or clarify the information with the relevant sources or authorities.

Answer 3

E None of the individuals will be alive 6 months later.
