The correct answer is (c) (i) and (iii).
Explanation:
Biodiversity refers to the variety of life on Earth, including the different species of plants, animals, and microorganisms present in a given area. It also encompasses the genetic diversity within these species and the ecosystems they inhabit.
Statement (i) correctly describes this broad definition of biodiversity, as it mentions the different species of flora and fauna present.
Statement (iii) is also correct. Forests typically have a higher diversity of species compared to other ecosystems due to their complex structure and varied habitats.
Why the other options are incorrect:
(ii)
Biodiversity is not limited to only flora (plants); it encompasses all forms of life.
(iv)
This statement describes the concept of population size, not biodiversity. Biodiversity focuses on the variety of different species, not just the abundance of a single species.
