उत्तर

Tropics

Explanation:

The tropics have the most biodiversity because they have less seasonal fluctuations and hence remain undisturbed.

Temperate environments are more seasonal, have less Wnstand, and have fewer species variety; yet, alpine locations with cold temperatures and high elevations have diversity.
