Which regions of the world tend to have the greatest species richness?

regions near the equator
warm, desert-like regions
Species richness varies randomly across the globe, and no areas are particularly high in species richness compared to other areas.
areas high in mountains, where humans have not impacted the environment

Option (1)

Explanation:

The richness in the species depends upon various factors, such as the availability of the nutrients, energy, favorable climate, amount of precipitation, and some others.

The equator is the region that receives the maximum amount of sunlight and rainfall. This region attains the maximum of all the energy that helps in the increasing number of species. So, there occurs a high richness in the species in the equatorial and its nearby region.

Thus, the correct answer is option (1).
