- Which of the following choices would most likely promote random distribution?
 - Territorial species
 - Species that secrete chemicals to attract or inhibit other individuals
 - Spacing during breeding season
 - Homogenous chemical and physical factors in the environment
 
- All of the following statements about logistic model of population growth are correct EXCEPT:
 - Populations will increase in size indefinitely
 - It describes a population density shift overtime
 - It fits an S shaped curve
 - It predicts an eventual state in which birth rate equals death rate
 
- Which of the following best describes a cohort?
 - A group of individuals from the same age group, from birth until they are all dead
 - The reproductive males and females within the population
 - A group of individuals that inhabits a small isolated region within the range for the species
 - The number of individuals that annually die or emigrate out of a population
 - As N approaches the carrying capacity (K) for a certain population, which of the following is predicted by the logistic growth curve?
 - The carrying capacity of the habitat will increase
 - The growth rate (r) will approach zero
 - The growth rate (r) will not change
 - The population will increase exponentially
 
- Which population would be most likely to experience exponential growth?
 - A young population with few individuals
 - A population with a large number of individuals
 - A population living in a habitat with a low carrying capacity
 - A population living in a habitat with limited resources
 
- Which of the following hypothesis explains the scenario: rabbit (primary consumers) populations will crash when lynx (their predators) populations are high?
 - Predator-prey
 - Consumer index
 - Bottom-up
 - Top-down
 
- Why do populations grow more slowly as they approach their carrying capacity?
 - Density dependent factors lead to fewer births and increased mortality
 - Density independent factors lead to fewer births and increased mortality
 - The incoming energy decreases in populations experiencing a high rate of increase
 - Individuals voluntarily stop mating so that overcrowding doesn’t occur
