- By mean of photosynthesis, carbon dioxide and water are transformed into a number of organic molecules in plant cells.
- Nitrogen fixation from the soil into organic molecules by symbiotic bacteria which live in the roots of certain plants, such as Leguminosae.
- The absorption of nutrients into the body after digestion in the intestine and its transformation in biological tissues and fluids
