Answer:
d. Species diversity
Explanation:
The species diversity can be measured by:
- Species richness: Refers to the number of species are inhabiting a defined area.
- Species abundance: Describe the distribution of the species abundance.
Species richness is the number of species present in a sample, within a community, habitat or microhabitat, ecosystem, landscape, region or any well-defined spatial unit. It is a metric for measuring biodiversity which simplicity and easy interpretation make it a standard metric. It is the simplest and straightforward measure of biodiversity. It is just a count of species, with no need for abundance data. In some cases, this can be the cause of criticism, as it ignores information about the species-abundance distribution.
