Questions and Answers

What is the relationship between species richness and latitude?

  • Species richness decreases as latitude increases
  • Species richness remains constant regardless of latitude
  • Species richness is highest at the poles
  • Species richness is greatest near the equator (correct)
  • What is the species-area effect?

  • The relationship between species richness and relative abundance
  • The pattern of species richness increasing with increasing area (correct)
  • The pattern of species richness increasing with increasing latitude
  • The effect of habitat destruction on species diversity
  • What is a consequence of the species-area effect?

  • Species richness is not affected by area
  • Habitat destruction can lead to species extinction (correct)
  • Habitat destruction has no impact on species richness
  • Larger areas support fewer species
