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 carbon footprint is the amount of GHG produced from an activity or a product. What would be the carbon footprint of a power plant producing electricity from coal. Calculate the GHG emission of CO2 per kWh of electricity produced. Assume the energy efficiency of the power plant as 38% and the heating value of coal as 4500 Kcal/Kg. Assume coal is 50% carbon. The answer you will get is also known as the emission factor for a coal power plant.
AP Environmental Science 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.
Questiion: A given ecosystem has the following amounts of energy available at each trophic level: Primary producers: 3,000 gC/m2/day; Primary consumers: 450 gC/m2/day; Secondary consumers: 45 gC/m2/day; Tertiary consumers: 2.25 gC/m2/day. Does this ecosystem follow Lindeman’s Law for ecological efficiency? A- No, the average efficiency is 20% B- Yes, the average efficiency is 20% C- Yes, the average efficiency is 10% D- No, the average efficiency is 10%
What is the range of values for percentage of emissions from transport of food to retailers (delivery)? Weber and Mathews found that 83% of food’s total emissions came from its production process on the farm or feedlot. What do these numbers tell you about how you might best reduce your own footprint with regard to food?

A group of researchers are assessing energy availability in a terrestrial ecosystem. 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. C - Plot 1 will show a decrease in rabbits and…
Which of the following statements BEST describes energy transfer in an ecosystem? A. If the primary producer has 175,000 kcal available, the secondary consumer will receive 17,500 kcal from the primary consumer. B. If the primary consumer has 175,000 kcal available, the secondary consumer will receive 17,500 kcal from the primary consumer. C. If the primary consumer has 175,000 kcal available, the tertiary consumer will receive 175 kcal from the secondary consumer. D. If the primary producer has 175,000 kcal available, the tertiary consumer will receive 17,500 kcal from the secondary consumer.
