Which of the following factors does NOT affect species richness?

In an experiment, two groups of paramecium species are grown together in a contained environment. P. aurelia grew well after 18 days, while P. caudatum declined to extinction over 18 days. This result demonstrates which of the following?

A country has a net immigration rate of 3 per 1,000; a crude birth rate (CBR) of 9 per 1,000; and a crude death rate (CDR) of 11 per 1,000. What is the growth rate of this country?

Which of the following describes the shape of the logistic growth model with time as the independent variable and population growth as the dependent variable?

Which of the following is an r-adapted species?

Which of the following population descriptions portrays the number of individuals in a particular age category?

Questions 7-9 refer to the following graphs:

Which example fits the growth pattern shown in Graph II?

Which letter on the graphs represents a population’s carrying capacity?

Which letter on the graph represents exponential growth?

The average number of offspring required to offset the average number of deaths in a population so that the population remains stable is referred to as:

Question 11 refers to the following graph:

During which phase(s) of the demographic transition does the death rate decline while the birth rate remains high, causing the population to grow rapidly?

Question 12 refers to the following age structure diagram:

A country with an age structure like the one shown above will experience:

Which of the following illustrates a global impact related to population growth?

Which line on the chart CORRECTLY matches the traits for K-selected and r-selected species?

Racoons are found in urban, suburban, rural, and wild settings. Because they can make use of a wide range of habitats and resources, they are considered:

A factor that influences an individual’s ability to survive and reproduce based on the size of a population in a given area is known as a:

A country with a high birth rate and a high death rate, where many children are born but few people make it to middle and old age, has an age structure diagram that looks like what?

According to the theory of demographic transition, a population in phase four would show which type of population growth?

Type I survivorship curves show that the number of survivors remains stable early but eventually decreases sharply at a particular upper age limit. Type II survivorship curves show that the number of survivors steadily decreases with an increase in age.

Which of the following can you determine from the descriptions of survivorship curves provided above?

Which of the following factors lead(s) to a declining birth rate in countries transitioning from phase two to phase three in the demographic transition model?

I. More women tend to stay home as a country becomes more developed, leading to decreased birth rates

II. More women tend to earn advanced degrees in developed nations, so they enter the workforce and have less time to raise children

III. There are more opportunities to own businesses in developed nations
