hey so I have an odd set of questions for you

so if two metal containers had soil of the same quality and one had only soil in it and the other container had soil in it but there was a body of a human that was decaying in it. So my question is, will a plant then grow faster in the normal soil or the soils with the human which has already decayed?

also, I've always wondered, if a dead human was put in a container that was air right, how will the decay process occur? Slower? Faster?

thanks, I've asked my friends but they have no idea and Im just curious

Q1. once the human body had largely decomposed it would release nitrogen and nutrients so I would assume the plants would grow better.

Q2. an absence of air/oxygen will significantly inhibit decomposition
