What is the matter that moves through an ecosystem?

Sunlight is the initial source of energy for most ecosystems. The producers convert light energy into chemical energy through photosynthesis. Energy transformations are yet never fully efficient and energy will escape from the ecosystem.The chemical energy then passes through the trophic levels of the ecosystem, where herbivores obtain energy from eating plants and carnivores obtain their energy from eating other animals. As for decomposers, they obtain their energy from waste products. Energy cannot be fully transferred between the trophic levels and it is only around 10% efficient as some energy is lost as heat through respiration.


What is flow of energy in ecosystem?

Energy flows from one trophic level to the next (Producer->Primary Consumer->Secondary Consumer). Energy transfer becomes less efficient as it's being transferred; seeing as it is partly used by the organism for metabolic processes.


What proportion of your electricity is generated using nuclear energy?

World wide the figure is about 16 percent


How do you calculate the efficiency of energy transfers?

Only 10% of the energy in one level gets to the next. The other 90% is used on movement. If you can figure out how much energy is in one trophic level, you can get how much energy gets to the next level by multiplying it by 0.1


What percent of women have the hourglass figure?

only 8 percent of women have an 'hourglass' figure.


How much energy is saved per degree using an air conditioner?

For every degree that you raise the air conditioner's thermostat, you can have a savings of two percent on the electric bill. A general method to figure out energy saved per degree is to know that every degree above 70 will increases the energy cost by 7 percent to 10 percent.

How does energy move through the tropic levels?

Figure 1: Trophic levels.The Transfer of Energy to Higher Trophic LevelsWhat happens to the NPP that is produced and then stored as plant biomass? On average, it is consumed or decomposed. You already know the equation for aerobic respiration: C6H12O6 + 6 O2 -------- 6 CO2 + 6 H2OIn the process, metabolic work is done and energy in chemical bonds is converted to heat energy. If NPP was not consumed, it would pile up somewhere. Usually this doesn't happen, but during periods of earth history such as the Carboniferous and Pennsylvanian, enormous amounts of NPP in excess of consumption accumulated in swamps. It was buried and compressed to form the coal and oil deposits that we mine today. When we burn these deposits (same chemical reaction as above except that there is greater energy produced) we release the energy to drive the machines of industry, and of course the CO2 goes into the atmosphere as a greenhouse gas. This is the situation that we have today, where the excess CO2 from burning these deposits (past excess NPP) is going into the atmosphere and building up over time.But let's get back to an ecosystem that is balanced, or in "steady state" ("equilibrium"), where annual total respiration balances annual total GPP. As energy passes from trophic level to trophic level, the following rules apply:Only a fraction of the energy available at one trophic level is transferred to the next trophic level. The rule of thumb is 10%, but this is very approximate.Typically the numbers and biomass of organisms decrease as one ascends the food chain.
