An example of a population is

• all trees in a forest
• all maple trees in a forest
• all plants in a forest
• all animals in a forest

The density of a population is

• the number of individuals born every year
• the proportion of males and females
• the number of individuals living in cities
• the number of individuals per unit area

Which of the following populations has a random dispersion?

• flock of flamingoes
• pine trees in a pine forest
• herd of bison
• solitary snakes in a desert

An example of something that causes density-independent deaths in a population?

• winter storms
• disease-carrying insects
• predators
• limited resources

Which of the following organisms has the highest reproductive potential?

• dogs
• elephants
• bacteria
• humans

Which statement best describes exponential growth?

• Each individual plant grows much larger than usual.
• The population immediately decreases
• Within a few years the population increases dramatically
• The species’ reproductive potential declines

The number of wild horses per square kilometer in a prairie is the horse populations

• density
• dispersion
• size
• birth rate

if every couple had only 2 offspring that lived long enough to reproduce, the population would

• grow
• shrink
• remain the same
• disperse randomly

Which of the following has the greatest effect on reproductive potential?

• producing more offspring at a time
• reproducing more often
• having a longer life span
• reproducing earlier in life

Which of the following is not an example of exponential growth?

• rabbit populations after being introduced to Australia
• reindeer of the Pribilof Islands after the food runs out
