Concept explainers
a.
To predict: The NPP of the desert scrub and tropical forest ecosystem types based on the temperature and precipitation profiles and the relationships between NPP and these environmental factors.
Introduction: The net primary productivity (NPP) is the rate at which primary producers produce dry biomass. It is generally expressed as grams of carbon. There are statistical relationships between NPP and environmental factors, such as temperature, precipitation, soils, solar radiant input, and vegetation structure.
b.
To compare: The estimate of the NPP calculated in +the previous part with what is reported in the given question.
Introduction: The net primary productivity (NPP) increases with an increase in temperature. The NPP also increases with precipitation up to about 240 centimeters per year and then decreases at higher levels.
