A temperate forest has GPP of 8,400 g/m²/year and plant respiration of 3,100 g/m²/year. What is its NPP?
An estuary's producers fix 6,200 kcal/m²/year through photosynthesis and use 1,700 kcal/m²/year in respiration. What NPP remains?
After a drought, grassland GPP is 3,600 g/m²/year and respiration is 2,400 g/m²/year. What is the grassland's NPP?
A phytoplankton community has GPP of 2,900 g/m²/year and respiration of 1,100 g/m²/year. Calculate NPP.
A restored wetland records GPP of 5,000 g/m²/year. Its emergent plants use 2,800 g/m²/year for respiration. What is NPP?
In a managed pine plantation, GPP is 7,500 g/m²/year and respiration loss is 4,600 g/m²/year. What NPP is stored as new biomass?
Algal producers in a nutrient-enriched pond have GPP of 4,800 g/m²/year and respiration of 3,900 g/m²/year. What is NPP?
A tropical rainforest has NPP of 6,100 g/m²/year and producer respiration of 4,300 g/m²/year. What is its GPP?
A field of biofuel crops has GPP of 5,600 g/m²/year and NPP of 2,100 g/m²/year. How much energy did producers use in respiration?
A kelp forest has NPP of 3,800 kcal/m²/year and respiration loss of 2,600 kcal/m²/year. Calculate GPP.
Urban tree cover has GPP of 2,700 g/m²/year and NPP of 900 g/m²/year. What is producer respiration?
A salt marsh has NPP of 4,200 g/m²/year and GPP of 6,700 g/m²/year. What is the respiration loss?
What does gross primary productivity measure in an ecosystem?
Why is NPP the productivity measure most directly available to consumers?
Two ecosystems have identical GPP, but Ecosystem A has greater producer respiration. How will their NPP values compare?
A forest's GPP rises after longer growing seasons, but its plant respiration rises by the same amount. What happens to NPP?
Use the bar graph. Which comparison of net primary productivity is supported?
Refer to the bar graph. Which ecosystem has the greatest net primary productivity per square meter?
Based on the graph, which pair has similarly low net primary productivity?
Use the bar graph. A developer converts 1 m² of estuary to open water. Which result does the graph support for annual NPP at that area?
