Competition and Predation Practice

What is the competitive exclusion principle?

• The competitive exclusion principle states that two species competing for the same limited resources cannot coexist in the same ecological niche for an extended period of time.

• The competitive exclusion principle is a theory that has been disproven by recent scientific research.

• The competitive exclusion principle only applies to plants and not animals.

• The competitive exclusion principle states that two species can coexist in the same ecological niche for an extended period of time.

Give an example of the competitive exclusion principle.

• The competitive exclusion principle states that two species can coexist even if they are competing for the same resources.

• Two species competing for the same resources can coexist if other ecological factors remain constant.

• Two species competing for the same resources cannot coexist if other ecological factors remain constant.

• The competitive exclusion principle only applies to plants and not animals.

Name one factor that influences competitive exclusion.

• Environmental conditions

• Predation

• Competition for resources

• Mutualism

How does competitive exclusion affect ecosystems?

• Competitive exclusion has no impact on ecosystems.

• Competitive exclusion increases biodiversity in ecosystems.

• Competitive exclusion only affects individual species within an ecosystem.

• Competitive exclusion can decrease biodiversity and disrupt the balance of an ecosystem.

Define predator-prey interaction.

• Relationship between two organisms where one hunts, kills, and consumes the other for shelter.

• Relationship between two organisms where one hunts, kills, and consumes the other for food.

• Relationship between two organisms where both hunt, kill, and consume each other for food.

• Mutualistic relationship between two organisms where both benefit from each other.

True or False: The competitive exclusion principle states that two species with identical niches cannot coexist in the same habitat.

• Sometimes true

• False

• Only in certain cases

• True

What happens to the less competitive species in competitive exclusion?

• The less competitive species becomes more dominant and outcompetes the other species.

• The less competitive species forms a symbiotic relationship with the more competitive species.

• The less competitive species evolves into a more competitive species over time.

• The less competitive species is either driven to extinction or forced to adapt and find a new niche to survive.

How does competitive exclusion impact biodiversity?

• Competitive exclusion reduces biodiversity.

• Competitive exclusion has a neutral impact on biodiversity.

• Competitive exclusion increases biodiversity.

• Competitive exclusion has no impact on biodiversity.

What is the role of resource partitioning in competitive exclusion?

• Resource partitioning helps species to coexist by reducing competition for the same resources.

• Resource partitioning increases competition and leads to competitive exclusion.

• Resource partitioning has no impact on competitive exclusion.

• Resource partitioning only affects individual species and not the overall ecosystem.

An organism's particular role in its habitat, or how it makes its living, is called its

• carrying capacity.
• ecosystem.
• competition.
• niche.
