In-Depth Information
TABLE 2.1 Net primary productivity of selected terrestrial and aquatic ecosystems. In most cases, data
represent individual systems where an annual production estimate was made. Note differences among systems
should not be interpreted finely (e.g., boreal forest has greater NPP than short grasslands) because the data do
not represent the range of possible NPP values for given system types, which are often wide.
