Biodiversity is the variety of living organisms on earth. Biogeochemical
cycles are the elemental cycles that exist on earth such as carbon, nitrogen,
phosphorus. It does not give value to biodiversity. The agricultural value of
pollinators such as bees carries pollen with them and delivers it from flower
to flower. They help flowers to produce more and at the same time gives a
variation to the physical and chemical properties of the flower. This is a
direct value of biodiversity. The answer is letter B.
