Question

question 8 of 10
what will happen if deforestation continues to destroy the green plants on the
planet?
a. the remaining plants will cycle all the air.
b. the excess co₂ in the atmosphere will increase global warming.
c. the excess co₂ will be absorbed into the ocean.
d. the remaining plants will increase their rate of photosynthesis.

Explanation:

Step1: Analyze function of green plants

Green plants absorb \(CO_2\) through photosynthesis.

Step2: Consider effect of deforestation

If deforestation destroys green plants, there are fewer plants to absorb \(CO_2\).

Step3: Relate \(CO_2\) and global warming

\(CO_2\) is a greenhouse gas. Excess \(CO_2\) in the atmosphere traps more heat, increasing global warming.

Step4: Evaluate other options

• Option A: Remaining plants can't cycle “all the air” as their number is reduced.
• Option C: While some \(CO_2\) can dissolve in the ocean, the main issue with deforestation - related \(CO_2\) is its role in global warming, not just ocean absorption.
• Option D: With habitat destruction and reduced resources (like space, nutrients due to deforestation), remaining plants are more likely to be stressed rather than increase photosynthesis rate.

Answer:

B. The excess \(CO_2\) in the atmosphere will increase global warming.
