Deforestation leads to an increase in atmospheric carbon dioxide because
ADecaying trees release carbon dioxide
BLiving trees remove carbon dioxide from the atmosphere via photosynthesis
CBurning wood releases carbon dioxide into the atmosphere
DAll of the above ✓ Correct
Correct answer: (D) All of the above — All these reasons apply, so the answer is all of the above.
Explanation
★All these reasons apply, so the answer is all of the above.
★When trees decay, they release carbon dioxide.
★Living trees would otherwise remove carbon dioxide through photosynthesis, and cutting them stops this.
★Burning the wood releases even more carbon dioxide.
★So deforestation raises carbon dioxide for all these reasons.
★So the answer is all of the above.
