Biology
A dead organism is more likely to become a fossil if it contains _________ parts like teeth or bones.
- Fossils are the preserved parts for many years so the parts have ability to resist decaying can become fossils only.
- Hard parts of organisms like shells, bones and teeth etc are made up of calcium carbonate which is very strong.
- So the hard parts have greater ability to don't decay and become fossils than the soft parts.
- As a result, an organism is more likely to become fossil if it contains Hard parts as compared to soft parts.
