The correct answer as to which is a measure of the biodiversity of an ecosystem would be the total number of different plant species present in the ecosystem. The correct option would be C.
By definition, biodiversity, also known as biological diversity, refers to the variety of living organisms present in a particular ecosystem. Biodiversity can be measured in terms of:
An ecosystem with 10 different species is less diverse than an ecosystem with 20 species, even if the population size of the former is more than the latter. In other words, the total number of individuals of a single animal species cannot be used to measure diversity.
Hence, the total number of different plant species found in an ecosystem can be a measure of the biodiversity of the ecosystem.
