Plants use energy from the sun for photosynthesis. You said it yourself, the energy splits water molecules. You're describing Earth ecology. | |
| Jan 21, 2017 at 20:50 | comment | added | pablodf76 | I understand that cosmic rays can be too strong, which is why I also asked about their subproducts (i. e. the secondary particles and radiation that they give off when they collide with the atmosphere). These an organism could use while staying inside the atmosphere. If energy could be extracted from them, an autotroph could use it to split useful molecules and build tissues. I haven't worked out that, since I wanted to check the basic point first. | |
