Answer:
Cellulose is found in abundance in nature in virtually all plant tissues and is therefore a common component of our diet. Humans cannot digest cellulose as their digestive system does not have cellulase, the enzyme which digests the cellulose .
Just like all living things, lichens need nutrients to survive and grow. The main nutrients include nitrogen, carbon, and oxygen. Nitrogen is especially important since it is necessary for the production of proteins and organic acids, and not just for lichens, but for life on this planet.
