What Gilbert has found, however, is that we overestimate the intensity and the duration of our emotional reactions -- our ''affect'' -- to future events. In other words, we might believe that a new BMW will make life perfect.
Carbon is present in the atmosphere in the form of a gas called carbon dioxide. During photosynthesis, plants use carbon dioxide from air and water molecules alongside the sun's rays to produce energy in the form of glucose. This takes place in the leaves, but is also a process adopted by algae and phytoplankton.
In this way, carbon dioxide from the air and water from the soil in a more disordered state are combined to form the more ordered sugar molecules. Carbon dioxide is captured in a cycle of reactions known as the Calvin cycle or the Calvin-Benson cycle after its discoverers. It is also known as just the C 3 cycle.
