Question:

Does the term 'biodiversity' relate only to the variety of organisms, or does it encompass other elements? [Pg. No. 247]

Answer: Verified

No, the term biodiversity does not relate only to the variety of organisms. It includes the variety of living organisms, the differences within the same species, and the variety of ecosystems in which they live. Thus, biodiversity includes genetic diversity, species diversity and ecosystem diversity. It also reflects the relationships among organisms and their surroundings, but it mainly refers to the diversity of living forms and their natural habitats.
