Morphology
The meaning 'to eat or be sustained by X' is directly derivable from combining 'feed' (to eat or nourish) with the preposition 'on', which signals the source or basis; a B1 learner who knows both words can infer this compositionally. This verb+preposition pattern is a common, cross-linguistic way to mark what something eats or relies on, so even the figurative senses remain largely interpretable.
Etymology
Feed on comes from a simple picture: an animal eats a certain food, for example a bird feeds on seeds or a fox feeds on mice. By the same idea, people can 'feed on' ideas, support, or excitement, meaning they get energy or help from those things, so the phrase also means 'to be supported or inspired by'.
