What characterizes wet warm ecosystems in relation to ET and NPP?

Wet warm ecosystems, such as tropical rainforests or wetlands, are characterized by high rates of evapotranspiration (ET) and high net primary productivity (NPP).

The high ET in these ecosystems results from the warm temperatures and abundant moisture, which provide optimal conditions for water loss through evaporation and transpiration from plant leaves. This process is crucial for maintaining plant health and growth, as it helps facilitate nutrient uptake and photosynthesis.

In addition, the combination of warm temperatures and abundant moisture supports a diverse range of plant species, which in turn leads to high NPP. NPP measures the rate at which plants convert carbon dioxide into organic matter through photosynthesis minus the carbon lost through respiration. In wet warm ecosystems, the favorable climatic conditions and rich nutrient availability enable plants to grow rapidly and produce a large biomass, contributing to a high NPP.

In summary, the interplay of high ET and high NPP in wet warm ecosystems creates a productive environment that supports diverse and abundant biological communities.
