HX Look at the table below containing cold tolerances of various pests in fields of corn. Average winter minimum temperatures in this area used to be 10 °F. Now the lowest minimum temperature in this area is 14 °F. Which field(s) would be predicted to show a decrease in com yield the following summer? Crop pest Cold tolerance (lowest temp. an organism can survive) A 28 °F B 12 °F C 20 °F D 24 °F OA.A OB.B OC.C OD.D

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

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.

Answer clearly

21. Decomposers are critical in the nitrogen and phosphorus cycles because they:   are responsible for the fixation of the nutrients into a bioavailable form allow for the cycling of the nutrients within the biosphere are involved in processes that return the nutrients to their major reservoirs More than one of these choices is correct.

P Parchment Exchange - Leader arn.edgenuity.com/player/ ce - SC5181 A 21 Unmark this X + gestion 01 M DELL TEXTO A ก A mature oak and hickory forest ecosystem experienced an intense forest fire that burned the existing trees the ground. Despite the intensity of the fire, some soils remained. Total biomass, species richness, and net productivity were reduced significantly after the initial disturbance. There have not been any more fires since. Twenty years after the fire, there are medium-sized trees and bushes growing, as well as ferns and flowering plants. The forest is in the middle, or intermediate, stage of succession. How has the current stage of succession affected total biomass, species richness, and net productivity of the ecosystem? O Total biomass remained the same, species richness decreased, net productivity remained the same O Total biomass increased, species richness increased, net productivity decreased O Total biomass increased, species richness increased, net…
