if we consider the sentence
birds consume spiders, and spiders consume flies
the "opposite" of that sentence is something like
is flies <> spiders and spiders <> birds but, more active. As if the spider jumps down the birds throat.
I'm looking for that word. Something similar to "feeds into", but just one word ideally.
https://www.merriam-webster.com/thesaurus/consume was not much help, I'm considering it in the second or third context, but from the point of view of the thing being consumed
