Exam 53: Population Ecology

Refer to the figure below to answer the following questions. Infant mortality and life expectancy at birth in developed and developing countries (data as of 2005). -In terms of demographics,which country is likely to experience the greatest population growth problem over the next ten years?

Which pair of terms most accurately describes life history traits for a stable population of grizzly bears?

Carrying capacity is

In models of logistic population growth,

Which of the following pairs of reproductive strategies is consistent with energetic trade-off and reproductive success?

Which of the following groups would be most likely to exhibit uniform dispersion?

Which of the following choices would most likely promote random distribution?

Which of the following scenarios would provide the most legitimate data on population density?

Use the survivorship curves shown below to answer the following questions. -Which curve best describes survivorship in marine molluscs?

A population is correctly defined as having which of the following characteristics? I.inhabiting the same general area II.belonging to the same species III.possessing a constant and uniform density and dispersion

The following questions refer to the description below. Theoretically,under ideal conditions,species can grow exponentially.In reality,however,species cannot maintain exponential growth indefinitely.Introducing species to habitats where conditions are optimal for that species often results in initial exponential growth. -One example of exponential growth was seen with the introduction of European rabbits into Australia.Within a short period of time the rabbit population in Australia exploded.This invasive species efficiently grazed vegetation in all habitats it colonized and before long spread throughout most of Australia.Many factors can contribute to the exponential growth rate of the rabbit population; which of the these factors would likely slow down population growth?

A population's carrying capacity

The three basic variables that make up the life history of an organism are

Which of the following examples would most accurately measure the density of the population being studied?

Why did the 2009 U.S.population continue to grow even though the United States had essentially established a zero population growth?

Which of the following statements does not apply to the logistic growth model?

Which of the following graphs illustrates the population growth curve of single bacterium growing in a flask of ideal medium at optimum temperature over a 24-hour period?

The observation that members of a population are uniformly distributed suggests that

Which of the following was the most significant limiting factor in human population growth in the 20th century?

In July 2008,the United States had a population of approximately 302 000 000 people.How many Americans were there in July 2009,if the estimated 2008 growth rate was 0.88%?
