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.
<span>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. </span>
A. they have a higher proportion of adenine–thymine than guanine–cytosine base pairs.
The option A represents the complete opposite of "high-gc gram-positive bacteria". High GC content means that this bacteria have more guanine ans more cytosine than the other base pairs- adenine–thymine. This means all the other options are correct.
