Net Primary Productivity
Net primary production and litterfall are intimately connected. In every terrestrial ecosystem, the largest fraction of all net primary production is lost to herbivores and litterfall. Therefore these factors must be accounted for. Ecologists account for this effect by subtracting the accumulated litterfall from the net primary production, resulting in what is called the true increment of net primary production. Due to their interconnectedness, global patterns of litterfall are similar to global patterns of net primary productivity.

Famous quotes containing the words net, primary and/or productivity:
“Afraid lest he be caught up in a net of words, tripped up, bewildered and so defeated—thrown aside—a man hesitates to write down his innermost convictions.”
—William Carlos Williams (1883–1963)
“The primary imperative for women who intend to assume a meaningful and decisive role in today’s social change is to begin to perceive themselves as having an identity and personal integrity that has as strong a claim for being preserved intact as that of any other individual or group.”
—Margaret Adams (b. 1916)
“It is ultimately in employers’ best interests to have their employees’ families functioning smoothly. In the long run, children who misbehave because they are inadequately supervised or marital partners who disapprove of their spouse’s work situation are productivity problems. Just as work affects parents and children, parents and children affect the workplace by influencing the employed parents’ morale, absenteeism, and productivity.”
—Ann C. Crouter (20th century)
