What is the main reason for the uneven distribution of plant and animal diversity in the world?
The distribution of species diversity is random.
Latitudinal gradient in diversity.
The biodiversity is the same everywhere in the worlD)
Polar areas have more species than temperate or tropical areas.
Solution
The diversity of plants and animals is not uniform throughout the world but shows a rather uneven distribution. With very few exceptions, species diversity decreases as we move away from the equator towards the poles, and the tropics (latitudinal range of 23.5° N to 23.5° S) harbor more species than temperate or polar areas.
