Questions and Answers

Which of the following best defines a niche in ecology?

  • The distribution and abundance of organisms
  • The study of biodiversity

  • The interactions between organisms and their non-living environments

    • Which of the following is an example of a limiting resource for organisms?

  • Distribution
  • Space (correct)

  • Abundance

    • What is the difference between the fundamental niche and the realized niche?

  • The fundamental niche is the role of an organism in its environment, while the realized niche is the range of physical and biological conditions needed for a species to maintain a stable population size.
  • The fundamental niche refers to the interactions between organisms and their non-living environments, while the realized niche refers to the distribution and abundance of organisms.
