Explanation:

Biodiversity simply defines the number of variety along with variability of organisms in an ecosystem.

Biodiversity is the result of diversity among different species and within a species. Hence, a small pond with 1300 organisms belonging to 26 different species exemplifies biodiversity best.

Although the pond may be small, it may support optimal living conditions for various types of organisms to grow and multiply in number and to live together in the aquatic ecosystem.
