Cycles Within Ecosystems
Akopọ
Carbon is the backbone of every organic molecule, yet there is only a fixed amount of it on Earth. The same carbon atoms that once formed the body of a dinosaur may now be part of a leaf, a lump of coal, or the air you are breathing out right now.
In this lesson you will trace the carbon cycle through its four main stages: photosynthesis, respiration, decomposition and combustion. You will see how carbon moves between the atmosphere, living organisms and fossil fuels, and why human activity is disrupting the balance.
