A scientist was studying a population of fish in a pond over a period of 10 years. He observed that
the population increased each year for 3 years, and then remained nearly constant for the rest of
the study. The best explanation for this observation is that the population had
stopped reproducing
reached carrying capacity
mutated into a different species
run out of food and all died
Which of the following best describes exponential growth in a population?
Population grows at a constant rate indefinitely.
Population growth slows as it approaches carrying capacity.
Population decreases over time.
Population remains constant over time.
What is the primary difference between exponential growth and logistic growth in populations?
Exponential growth considers carrying capacity, logistic growth does not.
Logistic growth considers carrying capacity, exponential growth does not.
Both models consider carrying capacity.
Neither model considers carrying capacity.
In a logistic growth model, what happens to the population growth rate as the population size approaches the carrying capacity?
The growth rate increases.
The growth rate decreases.
The growth rate remains constant.
The growth rate becomes negative.
Which of the following scenarios is an example of exponential growth?

A population of deer in a fenced area with limited food.
A population of bacteria in a petri dish with limited nutrients.
What does the carrying capacity of an environment represent?
The maximum number of individuals an environment can support.
The minimum number of individuals needed for a population to survive.
The average number of individuals in a population over time.
