What if we run out of atoms?? Interesting to learn that whatever happens to carbon, it always gets released back at soon stage.

[@lollmaohahaha]

Atoms can't be created or destroyed so that very unlikely.

[@user-sk7il1ur9s]

@@lollmaohahaha I'm pretty sure the subatomic particles can be separated, but it's unlikely to happen on a large enough scale and for long enough to ever make cause a deficit in atoms for us. But I think they can be created and destroyed; that's energy you're thinking of

amazing vid- could you do one on the rock cycle? sedimentary, igneous, metamorphic and all that jazz, id really appreciate it. thanks

[@vedantbhardwaj7582]

@Cognito Do you think this would be a correct explanation for the C cycle, and should I correct or add something? “In photosynthesis plants absorb carbon in the form of CO2 from the air. This carbon is then transferred to the form of glucose, from which respiration can be done by the plant, hence returning C atoms back into the air as CO2, or the C atom in the glucose can be used to synthesise other C-atom-contacting molecules such as carbohydrates, lipids or proteins, and become part of the plant’s biomass. The plant my then be eaten. Thus C-atoms from the plant’s biomass are transferred to the animal: some of which will be returned to the air in CO2, some will become part of the animal’s biomass, and some will be lost in waste such as faeces, or the animal’s dead body. The plant/animal’s dead body will then be decomposed by decomposers, who will respire, using the C-atoms from the animal’s biomass, returning C-atoms back into the air for plants to photosynthesise with. However, some dead animal/plant biomass may be in conditions that don’t allow decomposition to occur, such as a lack of O2. Thus, the biomass and waste will over millions of years of high pressure and heat will become fossil fuels. They can be then combusted and hence the C-atoms would be returned to the air and the cycle will repeat.” Thanks!!!
