Photosynthesis

Photosynthesis was a natural process by which plants gained sustenance. The Neti, an extinct sentient plant-like species, survived by this manner.

Forest trees on the planet Kothlis, a Bothan colony world, had broad fungus fronds that grew in the reddish light of the planet's star, maintaining Kothlis' Type I atmosphere through a crude form of photosynthesis. This process lent an odd fragrance to the planet's air smelling something like warm and moldy cheese.
