Describe how water
Alla [95]

Explanation:

Epipelagic zone, the topmost at the surface of the oceans receives most of the sunlight and most penetrating light rays diffuse in this layer. The temperatures at this zone, therefore, is warmer than zones below. This zone has lowest water pressure becaue there is little water column above it.

The deeper you get into the water the penetration of sunlight decreases. This is because the rays are greatly diffused even before they get to the deepest zones. The abyssalpelagic zone virtually receives no sunlight because the rays cannot get to this zone. This zone is, therefore, pitch dark and also the coldest. The deeper you get into the ocean the higher the water pressure due to the weight of the able water column. The water pressure is, therefore, highest in the  abyssalpelagic zone.

A grass snake living in northern England dies of natural causes. After a long period of time, its remains decay in the soil to b
Lubov Fominskaja [6]

Answer: C.  Dead snake fossilizing underground.

A fossil fuel is the fuel that is formed by natural processes, such as anaerobic decomposition of dead plants and animals underground. These organisms and their remains remain deep inside the depth of numerous layers of soil resulting in fuel produced after millions of years. A carbon sink refers to a natural or artificial reservoir that stores and absorbs atmospheric carbon by physical and biological process. The formation of fossil fuel inside the earth is carbon sink.  

Dead snake will be added as a matter on which biological activity called as decomposition will take place. The organic matter of dead snake will be decomposed by microbes in the soil. The organic matter being the source of carbon, after decomposition will become the reservoir of carbon in the form of fossil fuel.

Therefore, dead snake fossilizing underground is the example of carbon source becoming a carbon sink.
