(N/A) The biodiversity on our Earth is both astonishing and mesmerizing.
There are $20,000$ species of ants,$3,00,000$ species of beetles,$28,000$ species of fishes,and nearly $20,000$ species of orchids found on Earth.
Ecologists and evolutionary biologists are trying to understand the significance of this diversity through various questions,such as: $(i)$ Why are there so many species? $(ii)$ Did this diversity evolve throughout Earth's history? $(iii)$ How is it important for the biosphere? $(iv)$ What would be the effect on ecosystem functioning if this diversity were less? Most importantly,how can humans benefit from this diversity?
