Population Activities Analysis Quiz

Multiple Choice

What kind of biotic relationship was being demonstrated in the rabbit/fox and lynx/hare activities?

• Predation

• Competition

• Mutualism

• Parasitism

Draw

If there were no foxes in the activity we did outside,

what might the graph of the rabbit population look like over a time period?

Multiple Choice

The real life population growth model is most closely shown by

Multiple Choice

What caused the rabbit population to go up and down EVEN WITHOUT the presence of foxes in the environment?

• emigration due to lack of resources

• breeding due to unlimited resources

• competition for limited resources

• competition for unlimited resources

Multiple Choice

What happens if a population grows past its carrying capacity?

• The population keeps growing

• The population starts to die off

• The entire species will go extinct

• The carrying capacity just increases

Multiple Choice

The largest number of individuals that an environment can support long term is...

• carrying capacity

• emigration

• immigration

• population density

Multiple Choice

Something that regulates the size of a population is called...

• a limiting measure

• a limiting factor

• carrying capacity

• biodiversity

Multiple Choice

What is NOT a biotic factor that affects carrying capacity?

• Food / Prey

• Disease

• Mates

• Temperature

Multiple Choice

What answer has a list of only Abiotic Factors that can affect the carrying capacity?

• Sunlight, Oxygen, Water

• Habitat Space, Water, Food

• Water, Oxygen, Disease

• Disease, Food, Mates

Multiple Choice

Propose a reason the population of the prey could still change numbers without any predators being around?

• competition between the prey is still occurring

• predation has long lasting affects even when not present

• competition is happening between the predator and the preys

• The population numbers are not changing if predators are not there

Multiple Choice

How can you tell that carrying capacity has been reached?

• the graph plateaus (becomes flat)

• the graph increases rapidly

• the graph declines slowly

• you cannot tell on a graph

Multiple Choice

When lynxes are removed, the population of the hares still changes. Why?

• because the lynxes are eating them

• because there are other factors effecting the population

• because the lynxes can no longer help the hares survive

• none of the above

Multiple Choice

The Red dotted line represents

• Carrying Capacity

• Average of population

Multiple Select

Which scenarios best applies to the above graph?

• The fox population increased because they did not reach their Carrying capacity.

• The rabbit population stayed the same because the same number were born as were hunted

• The fox population increase because there are plenty of rabbits to eat.

• The fox population decreased, while the rabbit population increased.

Multiple Choice

What happened to the Hare population after the decrease in Lynx population in 1860?

• The decrease of lynx led to an increase in the amount of hares.

• The decrease of lynx led to a decrease in the hare population.

• The hare population stayed the same.

Multiple Choice

What causes competition to occur in an environment?

• Good conditions make resources plentiful.

• Organisms struggle for a limited resource.

• Members of a population have different roles.

• A population falls below the environment’s carrying capacity.

Multiple Choice

Carrying Capacity is

• the capacity of what one person can carry per day

• how many animals you have in your daily bag limit at the end of the year

• wildebeest at a watering hole with zebras

• the maximum number of population size that the ecosystem can support

Multiple Choice

Factors that drive population changes include

• the availability of resources.
• predation.
• both a and b.
• none of the above.

Multiple Choice

How would you describe the general trend of this population pattern?

• negative (decreasing)

• positive (increasing)

• cyclic (loss and gain in a repeating pattern)

• no trend

Multiple Choice

The best title for the graph shown would be

• Lynx and Hare

• Predator and Prey

• Population Cycles

• Population Changes in a Predator/Prey Relationship
