The correct answer is: Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere.
How do fossil fuels play a role in the carbon cycle? (1 point)
Fossil fuels are rich in carbon, and burning them releases carbon into the atmosphere.
Fossil fuels require a lot of carbon to burn, which takes carbon out of the atmosphere.
Fossil fuels are rich in carbon, and burning them returns carbon to the soil.
Fossil fuels require a lot of carbon to burn, which releases carbon into the atmosphere.

y'all shure
Yes, I'm sure. When fossil fuels such as coal, oil, and natural gas are burned for energy, they release carbon dioxide (CO2) and other greenhouse gases into the atmosphere. This process contributes to the carbon cycle by adding carbon that had been stored in fossil fuels back into the atmosphere, where it can influence climate change.

How is the majority of carbon transferred from plants and animals to the soil? (1 point)
Carbon dioxide from plant and animal respiration dissolves into the soil.
Carbon atoms from plant and animal waste dissolve into the soil.
The decay of dead organisms releases carbon dioxide from their bodies into the soil.
The decay of dead organisms releases some carbon atoms from their bodies into the soil.

The decay of dead organisms releases some carbon atoms from their bodies into the soil.
The correct answer is: The decay of dead organisms releases carbon dioxide from their bodies into the soil.
When plants and animals die, decomposition by microorganisms and other decomposers breaks down their organic matter, releasing carbon back into the soil, primarily in the form of carbon dioxide through respiration, as well as other compounds that can contribute to soil carbon content.
Is all of Earth’s carbon dioxide supply constantly being used by organisms? (1 point)
Yes, and it briefly passes through the atmosphere as it cycles between organisms.
Yes, and it is used up as soon as it is formed.
No, some is stored in Earth’s carbon sinks, such as the oceans.
No, some is stored in Earth’s only carbon sink, the atmosphere.
Yes, and it briefly passes through the atmosphere as it cycles between organisms.
Yes, and it is used up as soon as it is formed.
No, some is stored in Earth’s carbon sinks, such as the oceans.
No, some is stored in Earth’s only carbon sink, the atmosphere.
The correct answer is: No, some is stored in Earth’s carbon sinks, such as the oceans.
While carbon dioxide is constantly being cycled through various organisms and processes, a significant amount is also stored in carbon sinks like the oceans, soil, and forests. These sinks hold carbon for varying periods, contributing to the overall carbon cycle.
Which of these is the largest living carbon sink? (1 point)
forests
insects
ocean
soil
forests
insects
ocean
soil
The correct answer is: ocean.
The ocean is the largest living carbon sink, storing a significant amount of carbon dioxide and organic carbon. It plays a major role in the global carbon cycle by absorbing CO2 from the atmosphere and supporting various marine life that contributes to carbon storage.
