Gause’s principle describes which concept?

Answer: Competitive exclusion.

  • A Competitive exclusion
  • B a resource partition idea
  • C only niche overlap
  • D the predator prey

Correct answer: A. Competitive exclusion

Explanation: Gause’s principle is the competitive exclusion principle.

Exponential (J-curve) vs Logistic (S-curve) GrowthtimePopulation (N)Exponential (unlimited resources)K (carrying capacity)Logistic (limited resources)Logistic growth slows as N approaches K; exponential growth never slows down

Exponential growth produces an ever-steepening J-curve with no limit, an unrealistic long-term model; logistic growth produces an S-curve that levels off at the carrying capacity K, as growth rate (K−N)/K shrinks to zero once resources are fully used.

Concept context

How organisms interact with abiotic factors and respond to stress, plus population attributes, growth models, and interspecific interactions such as predation, competition, and mutualism.
