Question

16 how does deforestation most likely affect atmospheric co2 levels? a atmospheric co2 levels increase. b co2 is converted to other elements and vanishes. c atmospheric co2 levels decrease. d no impact on atmospheric co2 levels.

Explanation:

Trees perform photosynthesis, taking in \( \text{CO}_2 \) from the atmosphere. Deforestation means fewer trees, so less \( \text{CO}_2 \) is removed from the atmosphere, and also, when trees are cut or burned, they release stored \( \text{CO}_2 \). This leads to an increase in atmospheric \( \text{CO}_2 \) levels. Option B is incorrect as \( \text{CO}_2 \) isn't converted to other elements and vanish. Option C is wrong because deforestation doesn't decrease \( \text{CO}_2 \) levels. Option D is incorrect as deforestation does impact \( \text{CO}_2 \) levels.

Answer:

A. Atmospheric CO2 levels increase.
