According to ecological principles, higher NPP typically results in what for higher trophic levels?

Net Primary Production (NPP) refers to the amount of organic matter or biomass produced by plants in an ecosystem that is available for consumption by herbivores and subsequently higher trophic levels. A higher NPP indicates a greater availability of energy and organic material, which directly supports increased populations of organisms at higher trophic levels.

When NPP is elevated, it means that there is an abundance of food resources available for herbivores. This increased food supply can support a larger population of herbivores, which in turn can support more predators. The energy transfer efficiency between trophic levels is not perfect, but with a greater biomass produced at the base level, the amount of energy available for herbivores and then for carnivores is also increased.

Furthermore, areas with high NPP often include diverse ecosystems, such as rainforests or wetlands, which provide various niches and resources that allow for greater population sizes and diversity among higher trophic level organisms. Thus, an increase in NPP generally correlates with more individuals present at higher trophic levels, allowing for a more dynamic and productive ecosystem.
