However, a plant that does not undergo photosynthesis is a dead plant especially since it is getting neither food or water from the soil. Also a plant does not produce oxygen for people, it is simply a by-product so Lion would not have a choice on whether or not his dimension  has oxygen. Anyway despite my thoughts, the theory is still good enough to stir debate so it should be flushed out  since it may be true. You do realize that not all plants are obligate autotrophs, right? There are non-phoyosynthetic plants you know, granted they are mostly parasitic in nature (one good example is the corpse flower,  Rafflesia  spp. or the ghost flower, Monotropa uniflora ). There are also carnivorous plants, but all are photosynthetic and only exhibit carnivory to offset the lack of nutrients in the soil they grow on.

But if Lion is a non-photosynthetic and non-parasitic plant, where does he get nutrients? Well, in Lion 2 we see Lion eating a gem lizard thing? Which would suggest that Lion is carnivorous. Oxygen, as said,  is just a byproduct of photosynthesis. Carbon dioxide is converted into organic sugars used by the plant. The plant also uses oxygen in respiration but that's another story. Since Lion exhibits carnivory, he no longer undergoes photosynthesis, as all the nutrients he needs comes from outside sources, ergo does not produce oxygen.
