Net primary productivity (NPP) can be defined as the amount of energy made available by plants to animals, only at the herbivore leve. The NPP of an ecosystem depends on different factors such as the levels of heat, moisture, nutrients available, competition ... If the NPP is low (little available food) than animals sparse (have to move to find it).
