  • Biodiversity refers to the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level.
  • It deals with biological and geographical units such as genes, chromosomes, species, families and biogeographic religions
  • It is an additional sum of genetic, taxonomic and ecosystem diversity.
  • Biodiversity is a measure of species richness i.e The number of groups of genetically or functionally related individuals.
  • Hence Biodiversity is a measure of the number of resources shared by the human population is a wrong statement.
  • So, the correct answer is 'Option C'.
