Answer 1

Explanation:

A ) decomposed organic material

Answer 2

The one which will not make a fossil is Option A: Decomposed organic material.

• Fossils are animal remains created from their body parts or traces while they were alive.
• After an animal has died, any body part that remains, such as loose animal bones, constitutes a fossil.
• Animal footprints and castings also become fossilised in the form of traces.
• Decomposed organic material, on the other hand, does not produce a fossil.
• To become a fossil, a component must last for a long time and not break down or decay.
• If any animal remains are buried beneath, they will become fossils if they are preserved from degrading by decomposers.
• Hence, decomposed material is not a fossil.
