Read the following passage.

Carbon is an extremely important element to many processes on our planet. Because Earth has a fixed amount of carbon, it is important for carbon to be used and re-used in a variety of ways. Carbon is moved through the environment via multiple processes. Two of these processes, photosynthesis and cellular respiration, take place in green plants. Cellular respiration also takes place in animals. Photosynthesis and cellular respiration can be pictured as opposites of each other, in a way. Photosynthesis uses carbon dioxide and water as reactants, and it produces glucose and oxygen gas. Cellular respiration uses glucose and oxygen gas as reactants, and it produces carbon dioxide and water.

Here is the same passage, but now it has the sentences numbered.
