Explanation:
Carbon fertilization refers to the positive effect of elevated carbon dioxide (CO2) levels on plant growth and productivity. When the concentration of CO2 increases in the atmosphere, plants have more access to this essential component for photosynthesis. As a result, they can enhance their photosynthetic activity and potentially increase their growth rate and yield. This phenomenon is particularly significant for C3 plants, which include the majority of plant species on Earth.
Increased carbon dioxide levels can act as a fertilizer for plants, leading to increased biomass production, improved water-use efficiency, and potential benefits for agriculture and forestry. However, it is important to consider the overall impact of rising CO2 levels on ecosystems, including potential interactions with other environmental factors such as temperature and nutrient availability.
