Scientists previously referred to the long-ago deposited plant and animal remains, now buried, compacted, and transformed into coal and oil, as the dead-end of the carbon cycle. since the industrial revolution, that would be an inaccurate statement. why?

It is inaccurate due to our use of coal and oil. It would be a dead end if it was left there, but we use items that use oil and coal in combustion and doing so release  Carbon dioxide into the atmosphere contributing to the carbon cycle.

The inaccurate statement is the end of carbon cycle.

Explanation:

Long time ago the deposited plant and animals are now being converted into coal. This coal was used in a enormous amount by the industries and factories. This cannot be considered as the dead end of the carbon cycle because the burning of fossil fuel releases carbon dioxide into the environment.

This carbon dioxide is used by plants to make glucose. Animals consume it and after sometime, the plants and animals dies to get compacted in soil.

This compaction again forms coal.So, there is no dead end of carbon cycle. hence,this statement was inaccurate statement.
