Yes, although the fossil record for the precambrian period is scarce.

Fossils are the remains of plants and animals that have been turned to stone.
fossil fuels r like decayed plants and animals (so FOSSILS) from 100 million years ago. they get turned into coal and oil and then drilled out.
When ancient animals and plants died, their bodies might be covered in silt, mud, sand, etc. Over an extremely long time, the sediment may be turned into sedimentary rock. The preserved remains are what we know as fossils.
Petrification =D
Most plants get nitrogen from fertilizers. Some plants can have a process called nitrogen fixing in which nitrogen from the is turned into ammonium compounds. Animals get their nitrogen from food, by eating plants and other animals.
By consuming plants that have used the sun's energy and turned it into food or by consuming animals that have consumed plants...or by consuming animals that have consumed animals that have eaten plante etc.
Fossil fuel is made from fossils that was under pressure for millions of years and turned into oil or coal. This can not be reproduced since there are no more fossils made from long extinct animals.
Millions of years of pressure and heat turned decaying animals and plants into coal.
The rock that forms is called a fossil.
Millions of years of pressure and heat turned decaying animals and plants into coal.
Most animals that became fossil fuels (coal, oil and natural gas) were tiny plankton in the oceans. Coal was made from larger vegetation and possibly animals like archosaurs, the reptile ancestors of the dinosaurs.
Their remains are subject to predation and decomposition before they have a chance to be covered in a layer of protective sediment that is normally associated with water erosion and deposition. The forest is not conducive to windblown or water carried sedimentation.
