Carbon Fertilization Definition
Question
Which of the following statements best describes "carbon fertilization"?
Options
Increased plant growth due to increased concentration of carbon dioxide in the atmosphere
Increased temperature of Earth due to increased concentration of carbon dioxide in the atmosphere
Increased acidity of oceans as a result of increased concentration of carbon dioxide in the atmosphere
Adaptation of all living beings on Earth to the climate change brought about by the increased concentration of carbon dioxide in the atmosphere
Explanation
Carbon fertilization is a well-established concept in ecology and plant physiology. It refers to the stimulation of plant growth that occurs when atmospheric CO2 concentrations increase. Plants use CO2 for photosynthesis, and higher concentrations can enhance photosynthetic rates and plant biomass production, particularly in C3 plants. Option (b) describes global warming/greenhouse effect, not carbon fertilization. Option (c) describes ocean acidification. Option (d) describes ecological adaptation. Carbon fertilization is specifically about the direct fertilizing effect of elevated CO2 on plant productivity. > Carbon fertilization = CO2 stimulates photosynthesis and plant growth directly. Answer: (a).
