I have been introduced to the term "phytomass" and I was wondering if phytomass can be both photosynthetic and non-photosynthetic?
"Biomass is defined as live material, necromass as dead, attached material. Biomass + necromass form the "standing crop" or phytomass." (from https://link.springer.com/chapter/10.1007%2F978-3-642-68786-0_22)
- But even if we were only talking about biomass, there is only a loose correlation between that and photosynthetic activity - think about single-celled algae, where 'every' cell is photosynthesizing, versus trees, where most cells are non-photosynthesizing, and there may even be times where none are (in trees that loose their foliage in winter).
