After a long, long time, the carbon from the remains of dead organisms can be stored in:RocksFossil FuelsWater

If animals and plants die in conditions where decomposing microorganisms are not present the carbon in their bodies can be converted, over millions of years and significant pressure, into fossil fuels

Formation of coal and petroleumCoal and petroleum have been formed from biomass which has been subjected tovarious biological and geological processes. Coal is the remains of trees, ferns, andother plants that lived millions of years ago. These were crushed into the earth,perhaps by earthquakes or volcanic eruptions. They were pressed down by layers ofearth and rock. They slowly decayed into coal. Oil and gas are the remains of millionsof tiny plants and animals that lived in the sea. When they died, their bodies sank tothe sea bed and were covered by silt. Bacteria attacked the dead remains, turningthem into oil and gas under the high pressures they were being subjected to.Meanwhile, the silt was slowly compressed into rock. The oil and gas seeped into theporous parts of the rock, and got trapped like water in a sponge. Can you guess whycoal and petroleum are called fossil fuels?

What name is given to the remains of organisms that lived many years ago, found in rocks?

Organisms contain carbonglossary term (opens in a new window). Sometimes, when an organism dies, the carbon in its body starts to break down. Some of the original material is decayed; however, the carbon also forms a dark coating on top of the dead organism. This preserves the organism’s body as a carbonized fossil. Carbonized organisms can be so well preserved, even details like the patterns or colors of skin or leaves can remain.

how can organic carbon be retained in the deep sea for hundreds or thousands of years? How does this relate to the role of the "solubility pump" in the main mechanism?
