What happens to my Corpse if I die in a Forest?

I was just randomly checking out what Funerals costs and was shocked how expensive it was! €3.500 to €5.500! I live in north Germany, and we have here some very deep Woods. So I was thinking what would happen if I just die there. Let’s say no one ever finds me. Are Animals just going to eat me, and will I just be gone in a couple of years?

EDIT: If someone knows what happens step by step I would be really curious to know :D
