Question
Which of the below mentioned regions exhibit lees seasonal variations?
Options
Tropics
Temperates
Alpines
Both Tropics and Temperates
Advertisements
Solution
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.
