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.
Could you mostly help me set it up and find it? So I can learn how to do it.
You are studying primary productivity and biodiversity patterns of an ecosystem. The ecosystem is represented by the climatograph below. The Gross Primary Productivity (GPP) is measured to be 5000 grams of carbon per square meter per year, and the Total Respiration (RT) is measured to be 300 grams of carbon per square meter per year.
- What kind of biome is this?
- Calculate the Net Ecosystem Production (NEP) for this ecosystem
- What does the calculated NEP value indicate about the carbon balance and overall productivity of the ecosystem? (one sentence)
- Based on both the climatograph and the NEP, what can you say about the biodiversity of plants versus consumers?
Choice 1 of 4:plant biodiversity is greater than consumer biodiversity
Choice 2 of 4:consumer biodiversity is greater than plant biodiversity
Choice 3 of 4:consumer biodiversity is the same as plant biodiversity
Choice 4 of 4:lower plant biodiversity compared to consumer biodiversity

The image shows the food web for this ecosystem. They set up three plots and assess the biomass of producers, primary consumers, and secondary consumers. Rabbits and grasshoppers feed on ground cover plants that grow on the forest floor. Plot 1 is composed of mature hardwood trees, and only 25% of the sunlight reaches the shrubs and grasses compared to plots 2 and 3, which have fewer trees and allow more sunlight to reach the forest floor. Based on the food web shown here, which of the following best describes how the reduction in sunlight to the forest floor would impact the number of primary consumers (squirrel, grasshopper, rabbit, and deer) in plot 1 compared to the other plots? A - Plot 1 will show an increase in deer only because they feed on trees. B - Plot 1 will show a decrease in squirrels and rabbits, while deer and grasshoppers will increase.
