You fossilize something by having it first fall in rock... then it gets covered in setimentary rock.... most likely and stays over in rock for many years. It then gets covered in rock and hardens and is fossilized!

Yes, a worm can be fossilized, but it is extremely rare, because it has no skeleton to be mineralized over time. So the only way you could find a fosssil of a worm is in a sandstone, because there it could have chances to be preserved.
Fossilized tree sap is called amber. It is formed when tree resin hardens and becomes buried in the ground, where it can undergo a process of polymerization over millions of years. Amber often contains prehistoric insects or other small organisms preserved within it.
Early organisms lacked skeletons and other hard structures that are most likely to be fossilized.

A biostrome is a horizontally-bedded stratum of fossilized remains of sedentary organisms.
Rapidly buried by sediments
Dead organisms that were living million / billion/S of years ago.
Less than 1% of all organisms that die become fossilized.

Amber is fossilized tree resin, while most fossils are made from the remains of organisms.
Fossilized remains of single-celled organisms similar to modern bacteria have been found in rocks more than 1.5 billion years old. These fossils provide valuable insight into Earth's ancient environments and the evolution of early life forms.
