Which of the following statements best describes “carbon fertilization”?
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
A.Increased plant growth due to 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
Carbon fertilization refers to the increased rate of photosynthesis in plants due to the rising concentration of carbon dioxide (CO2) in the atmosphere.
This increased photosynthesis can lead to enhanced plant growth.
The effect's magnitude varies based on factors like plant species, temperature, water availability, and nutrient levels.
Studies indicate that a significant portion (25-50%) of Earth's vegetated areas has shown increased greening in recent decades, largely attributable to rising atmospheric CO2 levels.
Hence, option A is the correct answer.
