Carrying Capacity Limiting Factor

By which activity can humans change the carrying capacity of the population of a species?

• Studying the niches (the role an organism plays in a community) of particular species.

• Manipulating resources in its natural environment.

• 
  Compiling a list of habitats in an ecosystem.

• 
  Convincing it to reduce its carbon footprint.

If the population of a species is greater than its carrying capacity for a long time, what can that do to available resources in its ecosystem?

• 
  Deplete them completely.

• 
  Nothing, as there is no causal relation.

• Double the amount that was there.

• Triple the amount that was there.

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

Biotic or Abiotic factor that restricts the growth of the population

• carrying capacity

• limiting factor

• abiotic factor

• biotic factor

Owls and snakes eat mice and other organisms. What would happen to the mice population if the owl population decreased?

• The population would decrease, as the loss of owls as part of their diet is a limiting factor.

• The population would decrease, as shelters created by owl nests is a limiting factor.

• The population would increase, as competition for food is a limiting factor.

• The population would increase, as predation by owls is a limiting factor.

Review the graph provided. What statements can be made about the significant decline in wolves around 1979?

• The wolf decline was a direct result of moose decline.

• The is no way to know why the wolf population dropped.

• The drop is most likely due to the declining moose population, but more information would be needed to determine that.

• The drop is most likely due to the increasing moose population, but more information would be needed to determine that.

• The wolf decline was a direct result of the moose increase.

How does the introduction of a new predator affect the carrying capacity of a prey species?

• Increases the carrying capacity

• Decreases the carrying capacity

• Has no effect on carrying capacity

• Doubles the carrying capacity

What is the carrying capacity of an environment?

• The maximum population size that the environment can sustain indefinitely

• The minimum population size needed for survival

• The average population size over a year

• The total number of species in the environment
