"By replacing the forest with pasture, you will clearly exacerbate drought and contribute to lower levels of fixed carbon."

The parameters of proximate analysis are moisture, volatile matter, ash, and fixed carbon.

This fuses together the fixed carbon and residual ash.

Cyanobacteria usually obtain a fixed carbon (carbohydrate) by photosynthesis.

The fixed carbon and nitrogen sources are exchanged through channels between the cells in the filament.

Up to 60% of the cells can become heterocysts, providing fixed nitrogen to the plant in return for fixed carbon.

The resulting seedlings obtain fixed carbon from the fungus until they produce their first leaves and begin to photosynthesize.

It contains a high percentage of fixed carbon and a low percentage of volatile matter.

Some orchids cheat by not providing fixed carbon to mutualistic fungi.

Much of this fixed carbon continues falling into the abyss, but a substantial percentage is redissolved and remineralized.
