There are always...
Worms, obviously.
Yes, there might be worms. That's why I have put into my will my desire, when I'm dead, to be put into a degradable sack, un-ebalmed, and buried in a big hole with a tree planted on top of me. If there is anything after I die like I perceive now, then, as fertilizer, I will become a part of the tree. 👍
