Question

Does energy cycle through an ecosystem? Explain how energy moves through an ecosystem. (You should be using terms such as:solar energy, decomposers, transfer, biomass, consumers, producers, heat, efficiency, cellular respiration). List two abiotic factors that producers (plants, algae, bacteria) need from their environment in order to be able to capture energy and turn it into biomass? Carbon Cycle: Carbon fixation occurs during _____ when sugars get built out of carbon dioxide. Carbon dioxide is released from organic carbon molecules by two main processes:_____ and __________. Name one large reservoir of inorganic carbon. [There is more than one right answer here.] Explain one of mans major impacts on the carbon cycle.

Explanation / Answer

14. A) Energy flows through the ecosystem in the form of carbon-carbon bonds. During respiration, the carbon-carbon bonds are broken and the carbon is combined with oxygen to form carbon dioxide. This process releases the energy, which is either used by the organism or energy is released in the form of heat. All energy comes from the sun and the ultimate fate of all energy is to be lost as heat. Energy doesn't get recycled.

The energy in most ecosystems flows through the food chain. In terrestrial ecosystems and most marine ecosystems, the energy flow starts in green plants that obtain solar energy. The plants are consumed by animals, bacteria and other creatures, which are themselves eaten by other creatures. At each step in the food chain, energy is lost as heat. Green plants use the process of photosynthesis to capture light energy, combine it with carbon dioxide and water, and then form sugars to store the energy chemically. The amount of energy present at each step is much less than than the previous step. This means that eventually, the energy is gone, and no further energy is left.

The concept of biomass is important. They further removed a trophic level is from its source, the less biomass it will contain. Pyramid of biomass in relatively little energy is available from one trophic level to the next. This means that a consumer has to consume a lot of biomass from the lower trophic level to get sufficient energy. If that biomass contains the pollutant, the pollutant will be taken up in large quantities by the consumer.

B) The non-living components of the environment are known as abiotic factors. Abiotic factors include things such as rocks and water. Temperature and moisture also influences plant production and the amount of organic matter available as food. Primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide. It occurs through the process of photosynthesis, which uses light as its source of energy. Chemosynthesis is the production of carbohydrates and other compounds using the oxidation of chemical nutrients as a source of energy rather than sunlight. It is limited to certain bacteria and fungi. Chemosynthesis uses the oxidation or reduction of chemical compounds for its source of energy. Almost all life on earth is directly or indirectly reliant on primary production.

15. Carbon fixation occurs during light reactions when sugar built out of carbon dioxide. These reactions uses the sunlight to generate energy inside the cell.
Biological process is peat production. Peat bogs are a very important carbon storage. Peat bogs act as a sink for carbon due to the accumulation of partially decayed biomass that would otherwise continue to decay completely. Physical process is ocean storage. In this process, CO2 were injected to the ocean bottom. The pressures would be great enough for CO2 to be in its liquid phase. The idea behind ocean injection would be to have stable, stationary pools of CO2 at the ocean floor.
Ocean is a large reservoir of inorganic carbon. CO2 were injected to the ocean bottom, the pressures would be great enough for CO2 to be in its liquid phase. This reservoir is stable and stationary pools of CO2 at the ocean floor. The ocean could potentially hold over a thousand billion tons of CO2.
Human impacts on the carbon cycle is burning of fossil fuels. Under natural conditions, the release of carbon from fossil fuels occurs slowly and CO2 is released through volcanic activity. However, humans are heavily reliant on fossil fuels, and extract it from the lithosphere in great quantities. Burning coal, oil, natural gas, and other fossil fuels for industrial activity and power generation removes the carbon from the fossil fuels and emits CO2 into the atmosphere.
