If bleeding is severe, or if you think there is internal bleeding, or the person is in shock, get emergency help. 1  Calm and reassure the person. The sight of blood can be very frightening.  If the wound affects just the top layers of skin (superficial), wash it with soap and warm water and pat dry.
Carbon is Important to Life. In its metabolism of food and respiration, an animal consumes glucose (C6H12O6), which combines with oxygen (O2) to produce carbon dioxide (CO2), water (H2O), and energy, which is given off as heat. The animal has no need for the carbon dioxide and releases it into the atmosphere. A plant, on the other hand, uses the opposite reaction of an animal through photosynthesis. It intakes carbon dioxide, water, and energy from sunlight to make its own glucose and oxygen gas.
Carbon is essential for the chemical processes that support life. It plays such an important role in life that sometimes we say that life is carbon-based. But there is only a limited amount of carbon on the earth. So carbon is constantly cycling around the earth, turning up in a lot of different forms and places. The reactions that move carbon around make up a giant web called the carbon cycle. Plants get carbon by taking carbon dioxide from the air. They use the carbon dioxide and the energy from sunlight to make food.
