Plankton and algae are examples of the material trapped in the sediment. They are not the only items trapped in the sediment that contributed. But Algae is a large portion.

Something I have often wondered is why did God create oil?
If you look at nature it seems to me that there is always a purpose for a plant or animal. I have often wondered what the purpose of oil is, what part does it play, God doesn’t do or create things with no reason. Anyone who can help me with this?

So could you please explain how we could get billions and billions of barrels of oil stored in unimaginably huge caverns (among other places) in the earth? How much algae and plankton would that take? And how exactly would it get there? And then what about natural gas?
