The correct response is:

The decay of dead organisms releases carbon dioxide from their bodies into the soil.

This process involves the breakdown of organic matter by decomposers, which results in the release of carbon into the soil in various forms, including carbon dioxide.

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 briefly passes through the atmosphere as it cycles between organisms.

No, some is stored in Earth’s carbon sinks, such as the oceans.

The correct response is:

No, some is stored in Earth’s carbon sinks, such as the oceans.

Carbon dioxide is not constantly being used; a significant portion is stored in various carbon sinks, including the atmosphere, oceans, and sedimentary rocks.

Which of these is the largest living carbon sink?(1 point)

insects

The correct response is:

ocean

The ocean is considered the largest living carbon sink, as it absorbs a significant amount of carbon dioxide from the atmosphere and stores it in various forms, including dissolved carbon and organic matter.
