Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During photosynthesis, carbon is moved from which reservoir (sink) to which reservoir (sink)?
A
From the atmosphere to the terrestrial biosphere.
B
From the troposphere to the terrestrial biosphere.
C
From the lithosphere to the terrestrial biosphere.
D
From the hydrosphere to the terrestrial biosphere
Explanation: 

Detailed explanation-1: -Carbon moves from one storage reservoir to another through a variety of mechanisms. For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis.

Detailed explanation-2: -Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms. These are the reservoirs, or sinks, through which carbon cycles. The ocean is a giant carbon sink that absorbs carbon.

Detailed explanation-3: -Carbon is in a constant state of movement from place to place. It is stored in what are known as reservoirs, and it moves between these reservoirs through a variety of processes, including photosynthesis, burning fossil fuels, and simply releasing breath from the lungs.

Detailed explanation-4: -A Carbon Sink – like plants, the ocean, and soil, are reservoirs that absorb more carbon dioxide (CO2) from the atmosphere than they release. It refers to a process called “carbon sequestration": natural or artificial deposits created where carbon would be stored for various periods depending on the medium.
