NPP (Net Primary Productivity)

Net Primary Productivity (NPP) is the amount of energy that plants in an ecosystem produce through photosynthesis minus the energy they use for their own growth and maintenance. It represents the energy available to herbivores, insects, and other consumers in the food chain. Essentially, NPP indicates how much new plant material is created that can support other life forms, playing a crucial role in sustaining ecosystems and absorbing carbon dioxide from the atmosphere. Higher NPP means more plant growth and more resources for animals and humans.
