Until recently, it was assumed that ultimately all ecologies depend on energy from the sun, that every living thing either directly creates its life from the sun through photosynthesis or indirectly by eating something else which did that (or like the lion eating something which ate something which got its energy through photosynthesis).
(something else; did; that) (the lion; eating; something which ate something) (something; ate; something which got its energy through photosynthesis) (every living thing; directly creates; its life) (something; got; its energy)
