Chemistry: All about Carbon

Decomposers, such as bacteria and fungi, break down organic matter from dead organisms, releasing carbon back into the atmosphere as carbon dioxide through cellular respiration.

Organic molecules, including carbohydrates, lipids, and proteins, are all based on carbon chains or rings, making carbon the fundamental building block of life.

Carbon's ability to form stable bonds with many other elements allows it to create the complex molecules (like DNA, proteins, and sugars) necessary for life.

Carbon dioxide is a greenhouse gas that traps heat in the atmosphere; therefore, an increase in its concentration leads to an increase in global temperatures.

Greenhouse gases like carbon dioxide trap heat from the sun, maintaining Earth's temperature within a range suitable for life.

Under specific conditions of heat and pressure over millions of years, buried organic matter transforms into fossil fuels like coal, oil, and natural gas.

Dry plant matter is composed of approximately 45% carbon by mass, as plants fix atmospheric carbon dioxide during photosynthesis.

Photosynthesis removes carbon dioxide from the atmosphere and releases oxygen as a byproduct, which is essential for the respiration of most living organisms.

Photosynthesis is the process that consumes carbon dioxide to produce glucose, whereas exhaling, combustion, and decomposition all release carbon dioxide into the atmosphere.

During photosynthesis, plants capture carbon dioxide from the air and use the carbon atoms to build glucose molecules.

A compound is a substance formed when two or more chemical elements are chemically bonded together. Carbon, when combined with other elements, forms various chemical compounds.

Carbon's unique ability to form stable bonds with many other elements, including itself, allows for the creation of an immense variety of complex molecular structures. These diverse structures interact with light in different ways, resulting in a wide range of colors.

Carbon is a fundamental building block of life, and it makes up approximately 18 percent of the human body by mass.

Carbon is the basis for all known life on Earth; all living organisms are composed of organic molecules that contain carbon.

Carbon has an atomic number of 6 and has four valence electrons, which allows it to form four covalent bonds with other atoms.
