The atmosphere has 4 layers: the troposphere that we live in near the surface of the earth; the stratosphere that houses the ozone layer; the mesosphere, a colder and lower density layer with about 0.1% of the atmosphere; and the thermosphere, the top layer, where the air is hot but very thin.
It is very interesting how photosynthesis and cellular respiration<span> help each other. During photosynthesis, the </span>plant<span> needs carbon dioxide and water-- both of which are released into the air during </span>respiration<span>. And during </span>respiration<span>, the </span>plant<span> needs oxygen and glucose, which are both produced through photosynthesis!
