Carlo Rovelli described in "The Order of Time" that "Living beings are made up of similarly intertwined processes. Photosynthesis deposits low entropy from the sun into plants. Animals feed on low entropy by eating. (If all we needed was energy rather than entropy, we would head for the heat of the Sahara rather than toward our next meal)." Is there any exception? Are there living things or any object that feed on heat of the Sahara rather than low entropy?
