- 1.GPP = 900 kcal/m2/year, respiration = 350 kcal/m2/year. Find NPP.
- 2.GPP = 1,500 kcal/m2/year, respiration = 600 kcal/m2/year. Find NPP.
- 3.A crop has plenty of water and nitrogen but very little phosphorus. Adding more nitrogen does not help growth. Explain why, using Liebig's Law.
- 4.Rank from most to least productive per unit area: desert, estuary, open ocean, tropical rainforest.
