Final answer:
Favorable conditions for fossil preservation include being covered by sediments, being frozen or trapped in resin, and preserving traces like footprints or burrows. Soft tissue is difficult to preserve and requires burial in special environments. Factors like temperature, light, water depth, and chemical conditions also affect fossil preservation.
Step-by-step explanation:
The conditions that favor the preservation of an organism as a fossil include being quickly covered by sediments or preserved in some other way, such as being frozen in glaciers or trapped in tree resin. Traces of organisms like footprints or burrows can also be fossilized. Soft tissue is difficult to preserve and usually requires burial in an oxygen-free, low-energy sedimentary environment. Factors like temperature, light, water depth, and chemical conditions also play a role in fossil preservation.
