As you have read, change in biomass over a given period is called biological production. Define and discuss the differences between gross and net production within a system. Additionally, discuss why biological production often differs in various ecosystems. Support your claims with at least two scholarly sources in addition to the textbook. According to our text book, gross production is the increase in energy absorbed through photosynthesis, before any respiration occurs. The amount of fixed carbon not used by plants (Britannica, 2014) is the net production left over after respiration has occurred. After the costs of respiration, the average plant net primary production efficiency is about 2-3% in land plants and about 1% in aquatic systems. One reason for diversity in the...
