The diagram shows a model that Peter made of the carbon cycle.

Question

Which mistake did Peter make in the model?

Plants do not lose carbon through respiration.

The burning of fossil fuel does not release carbon.

Organisms that decay do not deposit carbon in the soil.

Animals do not breathe carbon dioxide from the atmosphere.

Answer 1

Peter made the mistake that "The burning of fossil fuel does not release carbon."

This statement is incorrect because the burning of fossil fuels does indeed release carbon dioxide into the atmosphere, contributing to the carbon cycle. The other statements are also inaccurate, but this one explicitly misrepresents a key aspect of the carbon cycle process.
