<span>Both photoautotrophs and chemoautotrophs synthesize organic compounds from (inorganic) carbon dioxide, a process known as carbon fixation. Photoautotrophs get the energy to perform these reactions from light. Chemoautotrophs get it from electron donors such as hydrogen sulfide and ammonia. Cyanobacteria, by contrast, convert nitrogen from the atmosphere into ammonia, a process known as nitrogen fixation.</span>
Humans can make a difference but carbon is everywhere. This generation has the largest carbon footprint yet.
It doesn't absorb green light really well, but it would be blue and red light
1. theyre opposite because during photosynthesis CO2 is absorbed by plants and during respiration CO2 is emitted.
2. glucose is made during photosynthesis and serves as food for every (!) animal, and animals decompose glucose to CO2 during cellular respiration.
