Chapter 55, Problem 12TYU
WRITE ABOUT A THEME: ENERGY AND MATTER
Decomposition typically occurs quickly in moist tropical forests. However, waterlogging in the soil of some moist tropical forests results over time in a buildup of organic matter called "pear " In a short essay (100-150 words), discuss the relationship of net primary production, net ecosystem production, and decomposition for such an ecosystem. Are NPP and NEP likely to he positive? What do you think would happen lo NEP if a landowner drained the water from a tropical peatland, exposing the organic matter to air?

Primary Productivity Problems
Net Primary Productivity efficiency can be calculated for terrestrial producers when values for insolation energy, respiration loss and gross productivity are known. Use the equations below to answer the following problems:
Net Primary Productivity = Gross Productivity – Respiration Loss
Efficiency = . NPP . X 100
Insolation Energy
In a rice paddy in Southeast Asia, the insolation energy is 6,000,000 calories/m2/day. The gross productivity of the rice is 0.012 grams/cm2/day, and the respiration loss is 20 percent. One gram of rice is equivalent to 1000 calories.
Calculate the net primary productivity of the rice.
Find the efficiency of photosynthesis by the rice.
