decomposers turn organic material from corpses into simpler nutrients like nitrogen, phosphorus, and potassium. for example, proteins are broken down into amino acids, which then decompose into ammonium and nitrates. these nutrients are absorbed into soil and consumed by plants
tldr: plants eat corpses after decomposers turn them into nutrients
interesting. i’d say it’s not really that important, but then again i’d probably have a very different opinion if i didn’t have aphantasia.
