Cycles Within Ecosystems
Muhtasari
Carbon is the backbone of every organic molecule in every living organism, yet there is a fixed amount of it on Earth. The carbon cycle describes how this element moves continuously between the atmosphere, living organisms, the oceans, and the ground, recycled over and over again.
In this lesson you will trace carbon through the four key processes that drive the cycle: photosynthesis, respiration, decomposition, and combustion. Understanding the carbon cycle also helps explain why burning fossil fuels is altering the composition of the atmosphere.
Malengo
- Describe the stages in the carbon cycle, including respiration, photosynthesis, decomposition and combustion
