Coal. Or, some other hydrocarbon.
Carbonized remains form when organic matter such as plants or animals are burned in a low-oxygen environment. The high heat and lack of oxygen cause the organic material to break down and leave behind a carbon residue. These carbonized remains can provide valuable information about past ecosystems and climate conditions.

Things called decomposers break down the remains of dead plants and animals. They help to recycle the things in the plants and animals that can be useful to other plants and animals. They are the most numerous organisms in an ecosystem. Examples of decomposers include bacteria, fungi, some insects, and snails, which means they are not always microscopic.

Tiny remains of animals and plants in streams come from the mountains. When it rains, these remains are washed down the mountains toward the streams.

The biological accumulation of the skeletal remains of the plants and animals make up the fossils. A fossil refers to the trace of plants or animals that survived in the past.
A paleontologist studies fossilized remains of plants and animals.
The hardened remains of plants and animals are typically bones or fossils. Fossils are the hardened remains that are formed due to pressure from being squished between Earth's layers.
