Less than 1% of all organisms that die become fossilized.
Those that have body parts that are already mineralized. eg. shells and bones. A coral reef is a prime candidate.
No, b) a common ancestor.
Fossil fuel forms from the dead organisms acted on by temperature and pressure of the earth over millions of years.
Referred to as the "Cambrian explosion", most major animal groups first appeared in the fossil record beginning about 530 million years ago.
The evidence for the history of changing life forms on Earth is most often found in the fossil record. Fossils are the preserved remains or traces of ancient organisms that provide important information about the evolution of life over time. The study of fossils helps scientists understand how different species have evolved and diversified throughout Earth's history.

No, most animals and plants that have lived on Earth do not leave fossil evidence. Fossilization is a rare process that only occurs under specific conditions, so many organisms decompose before they can become fossils. This is why the fossil record is incomplete and biased towards certain types of organisms.
The fossil record of all species is not complete because the circumstances for fossils to occur is very rare. There must be a special type of sediment, a special type of death (not partially eaten). Therefore, not all species or mutations can be accounted for, however, there are documented fossils for most species or at least close relations
Hard structures like bones or shells are more likely to be well-preserved in the fossil record compared to soft tissues. Organisms that lived in environments conducive to fossilization, such as those with frequent sedimentation or low oxygen levels, are also more likely to have well-preserved fossils.
A fossil is evidence of an organisms existence, not a type of rock. Most fossils are found in sedimentary rocks.
Probably a trace fossil; evidences of an organisms existence, without the body. Trace fossils include footprints, feces, burrow marks, and chemical signatures.
Those that have body parts that are already mineralized. eg. shells and bones. A coral reef is a prime candidate.
Well its most likely everything will become fossil fuel from a human carcass,dog,cow and bugs.
Fossilization requires specific conditions to occur, so most organisms do not become fossils. Factors such as rapid burial, lack of decomposition, and the presence of minerals are needed to preserve the remains. As a result, the fossil record is incomplete and doesn't represent the full biodiversity that has existed on Earth.
Most of the species have become extinct.
A living fossil generally refers to a living organism, animal or plant, whose species has been around long enough on the planet to be part of the fossil record. Most fossilized species are extinct, but there are a few which are either still in existence, or have descendents which closely resemble them.
