Many rice-growing regions, especially in South and Southeast Asia, are in flood-prone lowland areas [].Flash flooding due to unpredicted rainfall is a common phenomenon in such areas, severely affecting rice crops in various stages of their development, requiring … The photosynthetic efficiency is the fraction of light energy converted into chemical energy during photosynthesis in green plants and algae. Photosynthesis can be described by the simplified chemical reaction 6 H2O + 6 CO2 + energy → C6H12O6 + 6 O2 where C6H12O6 is glucose (which is subsequently transformed into other sugars, starches, dominion virginia power smart meters
