Question

Gause's principle of competitive exclusion is, essentially,

• A. the more abundant species will exclude the less abundant species through competition
• B. competition for the same resources excludes species having different life styles
• C. no two species can occupy the same niche indefinitely when resources are limited
• D. larger organisms exclude smaller ones through competition as in the case of large trees controlling underbrush
  

Answer 1

The correct option is C no two species can occupy the same niche indefinitely when resources are limited

Gause's Law states that two species that compete for the exact same resources cannot stably coexist.
