Re: CHALLENGE: Why should there be an “origin of species”?

... Those that do not seem to be cycles might be simply too large for us to see in full. Please, report any that you think “complete” and non-cyclic in nature. Now, the question is, what is complete for you. Of course you can make one huge biochemical cycle starting with CO2 and ending with ...

Photosynthesis

... It appears that it is probably extremely unclear. I think it uses 4 photons per photosystem for each H2O broken.
