Which of the following statements best describes "carbon fertilization"?
A
Increased plant growth due to increased concentration of carbon dioxide in the atmosphere
B
Increased temperature of Earth due to increased concentration of carbon dioxide in the atmosphere
C
Increased acidity of oceans as a result of increased concentration of carbon dioxide in the atmosphere
D
Adaptation of all living beings on Earth to the climate change brought about by the increased concentration of carbon dioxide in the atmosphere
Correct Answer: Option A
Explanation
1. The question asks for the best description of "carbon fertilization".
2. Carbon dioxide (CO2) is a key input for photosynthesis, the process by which plants grow.
3. "Carbon fertilization" refers to the phenomenon where the increased concentration of carbon dioxide in the atmosphere leads to enhanced rates of photosynthesis and stimulates plant growth, particularly in certain types of plants (C3 plants), provided other resources like water and nutrients are not limiting.
4. Option (A) accurately describes this phenomenon: Increased plant growth due to increased concentration of carbon dioxide in the atmosphere.
5. Option (B) describes the greenhouse effect and global warming, not carbon fertilization.
6. Option (C) describes ocean acidification, another consequence of increased atmospheric CO2, but distinct from carbon fertilization.
7. Option (D) refers to adaptation to climate change, a broader concept not specific to the direct effect of CO2 on plant growth.
