The natural process by which the ozone layer get depleted are sun spots and atmospheric winds. The volcanic eruptions are also responsible for the depletion of the ozone layer.
The thinning of the ozone layer, which is present in the upper atmosphere is called ozone layer depletion. These natural processes causes and some chemicals compounds releases chlorine and bromine, which in exposure of high ultraviolet light causes the depletion of ozone.
The ozone layer found in the stratosphere of the earth atmosphere. This region protects the earth from harmful ultraviolet radiation of the sun. It has potential to absorb around 99% of the harmful ultraviolet radiation.
The main causes of ozone depletion are chloroflorocarbons, carbon tetrachloride, methylbromide. The natural processes does not cause more that 1 to 2 % of the ozone depletion.

<span>The Benedictâs test is used for studying the reducing sugars.
When the aldehyde is oxidized, the copper gets reduced and precipitates, changing the blue color of the solution to orange or red color.
The darker the color indicates that the solution has higher levels of sugar or a high amount of chemicals that have been reduced in the Benedictâs test.</span>
I think it is A as it's a desert it needs excessive sunlight as the animals have adapted to it.
