Detail about MCQs
Alpha diversity refers to the diversity within a particular area or ecosystem and is often measured by the number of species present (species richness) and their relative abundances (species evenness) within that area. It provides insights into the overall diversity at the local scale. Therefore, alpha diversity primarily relates to species diversity within a specific community or ecosystem.
