12. Which of the following statements best describes how trees help to reduce the negative effects of excess CO2 produced by humans:
The shade they provide slows down critical reactions in the carbon cycle
Mycorrhizal fungi on their roots transform the CO2 into CO
They incorporate carbon into their wood

The area under dispute covered about 260,000 hectares
