WRITE ABOUT A THEME: Energy and MatterDecomposition typically occurs quickly in moist tropicalforests. However, waterlogging in the soil of some moisttropical forests results over time in a buildup of organicmatter called “peat.” In a short essay (100–150 words), discussthe relationship of net primary production, net ecosystemproduction, and decomposition for such an ecosystem. AreNPP and NEP likely to be positive? What do you think wouldhappen to NEP if a landowner drained the water from atropical peatland, exposing the organic matter to air?
estimate the total primary production in the oceans (in million metric tons carbon) using the following information - 92% of oceans are open ocen with an average productivity of 125 gC/m2/yr - 8% of the oceans are coastal, with an average productivity of 2,000 gC/m2/yr - remember a metric ton is 1,000 Kg
Within an ecosystem, the total amount of energy produced initially by primary producers will be _ the total amount of energy lost as heat and respiration across all trophic levels, including producers, consumers, and decomposers. more than unequal to equivalent to less than
How can primary productivity be expressed/measured? O Both O New chemical energy per unit area and per unit of time O Neither O New biomass per unit area and per unit of time
ctional What proportion of energy stored at one trophic level ends up being LOST as it moves to the next trophic level? O 10% O 25% O 50% O 75% O 90%
Net ecosystem production is de fined as Onet primary productivity plus ecosystem respiration net primary productivity minus ecosystem respiration gross primary productivity minus autotrophic respiration gross primary productivity plus ecosystem respiration Ogross primary productivity minus ecosystem respiration
Figure 46.8 Why do you think the value for gross productivity of the primary producers is the same as the value for totall heat and respiration (20,810 kcal/ m2/yr)?
The total dry weight of plant material in a forest is a measure of the forests: a. gross primary productivity. b. net primary productivity. c. cellular respiration. d. standing crop biomass. e. ecological efficiency.
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.
