Solution

Species diversity is highest when species richness is high and relative abundance is evenly distributed.

Here's why:

  1. Species richness refers to the number of different species represented in an ecological community. The higher the number of different species, the higher the species diversity.

  2. Relative abundance refers to the proportion of each species in an ecosystem. When relative abundance is evenly distributed, it means that no single species dominates the ecosystem. This allows for a more diverse range of species to thrive.

Therefore, when both species richness is high and relative abundance is evenly distributed, it creates an environment where a large number of different species can coexist without any one species outcompeting the others, leading to high species diversity.
