<span>Carbon is present in the biosphere and other systems of the planet and is an essential part of life. Carbon moves through these systems by feeding the heterotrophs of other organisms, through the consumption of dead organisms. When oxygen is present, there is aerobic respiration, which releases carbon dioxide into the surrounding air or water. It plays an important role in the structure, biochemistry, and nutrition of all living cells.</span>
Answer:
What did researchers learn from terra preta?... Because terra preta is loaded with so-called bio-char -- similar to charcoal -- it also can pull substantial amounts of carbon out of the increasing levels of carbon dioxide in the Earth's atmosphere, helping to prevent global warming.
How is bio-char different from the traditional Amazonian method of creating terra preta? Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, broken pottery, compost and manure to the low fertility Amazonian soil. ... Terra preta soils were created by farming communities between 450 BCE and 950 CE..
The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.

Answer:
Processes of rock formation : Erosion & weathering, dissolution
Explanation:
Rocks are naturally occurring solid mass, or aggregate of minerals / mineraloil matter.
Processes that form rocks :
- Erosion & weathering - breaks down mountains & boulders into sediments
- Dissolution - Chemical weathering, acidic water wears away stones gradually
