No two species can occupy the same niche

• Competitive Exclusion Principle 

• Limiting Exclusion Theory

• Competitive Limiting Principle

• Limiting Competitive Theory 

The inevitable elimination from a habitat of one or two different species with identical needs for resources.

• Tertiary Consumer

• Organism

• Secondary Consumer

• Competitive Exclusion

More than one individual or population in an ecosystem that relies upon the same limited resource

Which of the following can be inferred from the graph showing the populations of different species of Paramecia grown in individual cultures (no competition)?

• P. aurelia outcompeted P. caudatum for the resources

• The carrying capacity for P. aurelia is higher than the carrying capacity for P. caudatum

• Both species of paramecia are competing for the exact same resource and being successful

Which of the following conclusions is supported by the graph showing the populations of 2 different species of paramecia grown together in a mixed culture?

• Both species of paramecia are able to survive when mixed in culture

• P. aurelia were able to get their needs met more easily than P. caudatum

• Mixing both species of paramecia in one culture ends up giving the same results as if the two species are grown separately.

When taken to a new habitat, non-native plants often threaten native plants of the new habitat.  Why do they do this?

• Non-native plants are able to mutate rapidly

• Non-native  plants cause native animals to relocate

• Non-native plants are able to be used for medicine

• Non-native plants compete with native plants for resources

What effect will an invasive species have on the carrying capacity of an ecosystem?

• The carrying capacity will increase

• The carrying capacity for everyone will decrease

• The carrying capacity will only decrease for those in competition for same resource

• The carrying capacity for all animals will stay the same
