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.
When groundwater is depleted, the ground surface above can sink down over time. This is called Land Subsistence. Thus, option "D" is correct.
<h3>What causes subsidence?</h3>
Subsidence is a phenomenon of lowering of the ground surface due to changes in the underground support. The phenomenon occurs in several places in the world due to the
- extraction of water
- oil
- and gas from the subsoil.
With this information, we can conclude that Land subsidence is related to human population growth.
Thus, option "D" is correct.

Answer:
The reasons why Adenosine Triphosphate is a common energy source for all organisms is that: 1. It is a high-energy molecule 2. ATP has an unstable structure compared to other high-energy molecules. 3. ATP has higher potential to transfer phosphate group.
Explanation:
The transfer of phosphate group from high energy molecule like the adenosine triphosphate (ATP) usually release energy that is required by most of cellular activities, thus this dephosphorylation process is an exergonic reaction. While other molecules like the GTP can give energy, these molecules are more stable structurally and breaking them down will not by energetically wise, thus there is need to use a less stable high energy molecules like the ATP which have the potential of releasing their phosphate radical more easily. This is the reason why all organisms make use of the ATP molecule as the only energy source.
