Q. Which of the following statements best describes "carbon fertilization"?
Researchers report that the CO2 levels expected in the second half of this century will likely reduce the levels of zinc, iron, and protein in wheat, rice, peas, and soybeans. Some two billion people live in countries where citizens receive more than 60 percent of their zinc or iron from these types of crops. Deficiencies of these nutrients already cause an estimated loss of 63 million life-years annually.
- 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 hr the increased concentration of carbon dioxide in the atmosphere
Answer: Increased plant growth due to increased concentration of carbon dioxide in the atmosphere
The CO2 fertilization effect or carbon fertilization effect suggests that the increase of carbon dioxide in the atmosphere increases the rate of photosynthesis in plants. The effect varies depending on the plant species, the temperature, and the availability of water and nutrients.
The carbon fertilization effect (CFE): the larger amount of carbon dioxide in the atmosphere that has resulted from rising anthropogenic emissions should help the growth of plants, which use carbon dioxide during photosynthesis. The effect ought to increase crop yields – and that is some good news for farmers, amid the overwhelmingly gloomy forecasts for other aspects of climate change.
