D. Provision of fresh water is a direct value of biodiversity.

Direct values of biodiversity refer to biological resources that give immediate satisfaction or enjoyment.

Two types of direct values of biodiversity are Consumptive use and productive use.

Fresh water is consumptive use. It is a direct value because we can access fresh water immediate from nature without it going through the market. Other examples of direct value for consumptive use are firewood, fodder and meat.

Answer from: lauriepdx

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.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports the evolution of earth due to chemical weathering.

hope it !
