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?

support or refute the following statements based on what you learned about energy flow, biogeochemical cycling, decomposition, trophic levels, and keystone species. You may add a diagram or illustration to support your answer. Planting mangroves is better than putting dolomite sand on the coast of the polluted Manila Bay.
This figure has three graphs that have important implications for understanding how carbon flow and elements cycle through ecosystems through decomposition. The figures show data on the decomposition rates in a tropical forest. Please select all of the statements that are reasonable of at least one of the figures. interpretations Daily rate of mass loss (k) from 0 to 50 days (b) 0.9 0.8 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0.0 0 Leaf mass remaining (percent) (a) 100% 80 4 60 40 20 0 0 50 100 150 Days of decomposition 12 16 8 Leaf solubility (mg C/g dry leaf) (c) Daily rate of mass loss (k) from 51 to 230 days 0.009 0.006 0.003 0.000 200 Trumpet tree Inga tree Kapok tree Brazilian firetree 250 2 3 Ratio of leaf lignin:leaf nitrogen 4 Relyea, Ecology, 9e, Ⓒ2021 W.

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.
