As Latitude Increases, Biodiversity Generally

Question

As latitude increases, biodiversity generally
A) Decreases
B) Increases
C) Stays the same

Accepted Answer

Biodiversity generally decreases as latitude increases because tropical regions near the equator have more consistent temperatures and greater primary productivity, supporting a wider variety of species. In contrast, polar regions have harsher climates and less primary productivity, supporting fewer species.
