In space, however, telescopes<span> are able to get a clearer shot of everything from exploding stars to other galaxies. Another </span>disadvantage<span> for ground-based</span>telescopes<span> is that the Earth's atmosphere absorbs much of the infrared and ultraviolet light that passes through it.</span>
Photosynthesis produces oxygen gas by the reaction of sunlight and carbon dioxide. Every living thing living in an ecosystem requires oxygen to breathe and to survive.
