when an organism dies, its soft parts often decay quickly or are eaten by animals. that is why only hard parts of an organism generally leave fossils. these hard parts include bones, shells, teeth, seeds, and woody stems.
Usually the bones of an animal are preserved in a fossil. All of the softer material decomposes eventually, leaving behind the bones or a cast of the animal that has been fossilized.

Yes, preserved footprints are examples of fossils.
A2. The soft parts of an animal are least likely to survive, for these will be degraded by bacterial and insect action, if not by larger scavengers. If an animal dies on the land surface the chances of fossilization are minute.Good preservation of a fossil depends greatly on the environment in which the animal dies. If it is a very fine-grained silt, the probability of preservation is good, particularly of fine detail. The environment is likely to be anaerobic, and even the body's internal bacterial flora may be unable to survive in an anoxic environment.One of the remarkable preservations was the Archaeopteryx fossil, on which even the feather detail may be seen. Discovered quite soon after Darwin had launched his Origin of Species.Unusual preservation localities include swamps, and the remarkable La Brea tar pits. Another unusual fossil preserve is that of insects and spiders preserved in amber originally a gum exudate from trees.
The fossil record is incomplete because not all fossils have been discovered. In actuality it is unlikely that all fossils will ever be discovered given the hit and miss nature of fossil discovery which usually occurs through educated guess work. The fossil record will likely never be complete.
A cast fossil is formed when minerals fill in an impression left by an organism.
In order to know which of these animal parts is most likely to be preserved as a fossil one needs to know the available choices for answers.
It is called a mold fossil, which can become a cast fossil. After the soft parts of the animal rot away, a cavity remains (the mold fossil) which becomes filled with hardened sand or mud (the cast fossil).
The fossil that can preserve a whole animal is called a complete or articulated fossil. It occurs when the entire organism is preserved with all its anatomical parts intact, often due to quick burial in sediments that prevent decomposition or disintegration. Examples of complete fossils include the exceptional preservation of insects trapped in amber or well-preserved dinosaur fossils.

organisms tend to decay before becoming a fossil. animals with hard parts are preserved more easily. geological processes may destroy fossils.
Well If you mean like preserved as in fossilized shell fish (clams and lobsters and such) have the highest fossilization record. The are more likely to be traped in sand, or mud at the bottom of the ocean. But this is just a quick guess
Any organism or parts of an organism counts as a fossil when preserved within amber, so fossils can be stored in amber.
Animal parts that are soft and don't have a skeleton leave the worst imprints. Fossils are made with animal parts that are hard and durable.
Any part of the body can be preserved as a fossil. The most common parts of the body to be fossilised are the hard parts such as claws, teeth and bones but it is also possible to fossilise soft tissue as well. One example of Thescelosaurus shows extensive soft tissue fossilisation. It was given the nick name of "Willo" the dinosaur with a heart.
hard parts on the outside of the organism means that the potential fossil is more likely to survive as increasing pressures are placed on the potential fossil when sediments are placed on top.
we eat every part of the clam, it might just depend on you (what you like)
