Group of answer choices a. evaporation b. net primary production c. standing crop d. nutrient limitation e. gross primary production
- Which of the following is a renewable energy resource? I. Solar II. Wind III. Geothermal IV. Natural Gas A. I and II only B. III and IV only C. I, II and III D. II, III and IVRank the following energy sources from highest to lowest carbon intensity. (1 being the highest, 4 being the lowest) Nuclear Natural gas Oil CoaAP 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.

Group of answer choices a. 37 g/m2/year b. can’t tell from the information given c. 50 g/m2/year d. 63 g/m2/year e. 25 g/m2/yearDeserts and semidesert scrub cover about the same amount of surface area as tropical rain forests but contribute less than 1% of Earth’s primary production, while rain forests contribute 22%. Explain this difference.A family travels from New York City to Costa Rica three times a year for a vacation. The family would like to purchase some forested land in the Catskills, keeping the trees intact as an offset to the carbon dioxide they produce travelling each year. How much forest must they purchase? Use the following assumptions to measure the carbon offset provided by this intact forest. • The biomass of the forest increases at an annual rate of 2.8 × 105 kg/ha. • The forest biomass is 45% carbon by mass. • There are four people in the family. • 0.2 kg of CO2 is produced each mile per person on the flight. • The round-trip distance is 4,500 miles. • There are 2.47 acres in one hectare. 1. Calculate the mass of carbon, in kilograms, that is accumulated and stored in 1.0 ha of this forest in one year. 2. Calculate the mass of carbon, in kilograms, that is emitted by the family as a result of their round-trip flights to Costa Rica each year. 3. Calculate the number of acres of forest that must be…
