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
