It looks to me that those are plant genes. And plant genes use the atmosphere and the hydrosphere to take in carbon dioxide. CO2 is in the atmosphere and once consumed, sugar ( Glucose ) is created. H2O is part of the hydrosphere and when water is consumed, Oxygen is the output. All of the spheres of the earth ( biosphere, hydrosphere, geosphere, and atmosphere ) are interconnected to create the things we know and see.
It’s a place that has lots of fish and they catch a lot fish there.
