Question

how may large - scale deforestation affect the amount of carbon dioxide and oxygen in the a by decreasing the amount of both carbon dioxide and oxygen b by decreasing the amount of carbon dioxide and increasing the amount of oxygen c by increasing the amount of carbon dioxide and decreasing the amount of oxygen d by increasing the amount of both carbon dioxide and oxygen

Explanation:

Trees perform photosynthesis (take in \( \text{CO}_2 \), release \( \text{O}_2 \)) and respiration. Deforestation reduces trees, so less \( \text{CO}_2 \) is taken in (so \( \text{CO}_2 \) increases) and less \( \text{O}_2 \) is released (so \( \text{O}_2 \) decreases). Option C matches: increasing \( \text{CO}_2 \), decreasing \( \text{O}_2 \).

Answer:

C. by increasing the amount of carbon dioxide and decreasing the amount of oxygen
