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.

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.
Amber can sometimes preserve a whole animal. This would be called a mold fossil. Body freezing is another way in which an entire animal can be preserved. Scientists have found mammoths preserved in this manner.
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).

Those that have body parts that are already mineralized. eg. shells and bones. A coral reef is a prime candidate.
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
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.
Organisms that have hard parts such as bones, shells, or teeth are more likely to form fossils. Soft-bodied organisms can also be preserved in certain conditions, such as being quickly buried in sediment or trapped in amber.
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.
