Questions and Answers

Which of the following best describes the concept of 'Carrying Capacity'?

  • The maximum population size an environment can sustain. (correct)
  • The variety of genetic characteristics in a population.
  • The amount of biomass available in an ecosystem.
  • The total number of species in a specific area.
  • What effect does habitat fragmentation have on biodiversity?

  • It increases genetic diversity within species.
  • It enhances connectivity between habitats.
  • It leads to isolated populations, reducing species diversity. (correct)
  • It decreases competition among species.
  • Which statement accurately reflects characteristics of R-selected species?

  • They have a high reproductive rate and rapid population growth. (correct)
  • They typically produce few offspring with high parental care.
  • They are highly specialized and occupy unique ecological niches.
  • They thrive in stable environments with little competition.
