It’s mostly algae and other plant matter, but yes; things that died a long time ago get buried and break down slowly into more basic hydrocarbons. Depending on the precise pressures and local geology involved, they turn into various hydrocarbon substances ranging from gases (e.g. methane and other natural gases), liquids (crude oil), and solids (i.e. coal).
