Answer:
D. count the number of species, and measure their relative abundance.
Step-by-step explanation:
Biodiversity refers to the wide variety of living beings that inhabit the Earth as well as the results of billions of years of evolution according to natural processes and also the influence of human activities.
This makes it a concept to measure because of the number of subelements that encompass it, however, have been made several approaches to arrive at a valid method.
The simplest diversity measures consist of mathematical indices that express the amount of information and the degree of organization of the same.
As far as biodiversity is concerned, three aspects are measured:
Wealth: The number of elements. Depending on the area, heterozygous (genetic level), number of species (specific level), or the number of different habitats or environmental units (ecosystem level) are referred to.
Relative abundance: The relative incidence of each of the components in relation to the others.
Differentiation: It is the degree of genetic, taxonomic or functional differentiation of the elements.
Each of these indices of diversity is one-dimensional and of limited reading since the comparisons and valuations of biological diversity are incomplete because they are insufficient.
