Detailed explanation-1: -They should note that the soft parts of plants and animals decompose quickly. The hard parts (bones and shells) of animals and the hard, woody parts of plants take the longest to decompose. The less a living thing decomposes, the more likely it is to become fossilized.
Detailed explanation-2: -Fossilization is rare. Most organisms decompose fairly quickly after they die. For an organism to be fossilized, the remains usually need to be covered by sediment soon after death.
Detailed explanation-3: -The fossil record is considered to be incomplete because fossilization is a very rare phenomenon. Most organisms decompose quickly after their death, and their remains dispersed. In order for fossilization to occur, the remains have to be covered by sediments and stay undisturbed for thousands of years.
Detailed explanation-4: -The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils.
