Scientists Currently Estimate NPP Using Which Type of Measurement

Question

Scientists currently estimate NPP using which type of measurement?
A) Wavelengths of light reflected from Earth's surface
B) Amount of nitrogen fixation
C) Atmospheric O2concentrations
D) Atmospheric CO2concentrations
E) Total yearly plant biomass

Accepted Answer

Scientists estimate Net Primary Productivity (NPP) by measuring the wavelengths of light reflected from Earth's surface, which helps determine the amount of photosynthesis occurring in plants. This method is often used in remote sensing technologies.
