How does non-human life in an urban ecosystem differ from non-human life in an undeveloped forest ecosystem? (Site 1)

ahrayia [7]

Answer:

- Urban ecosystem: highly disturbed systems. Air, water and soil pollution by various pollutants.

- Undeveloped forest ecosystem: non disturbed systems. Low or null levels of pollution.

Explanation:

An urban ecosystem can be defined as the community of plants, animals, and humans inhabiting an urban environment. Urban ecosystems are composed of human-built physical structures (e.g., buildings, roads, sewers, railways) and green patches (e.g., parks, greenways, urban streams). In general, urban ecosystems are highly disturbed and contain high levels of pollution. In urban areas, plant life is generally overrepresented by non-native and invasive species. Moreover, animal life primarily consists of pets (e.g., dogs, cats, ornamental birds, ornamental fish) and natural species adapted to human activities, which mainly include small animals (e.g., insects). Moreover, a forest ecosystem is defined as a natural woodland unit composed of 1-biotic factors such as plants (e.g., trees) animals (e.g., insects, birds) and micro-organisms, and 2-abiotic factors (e.g., water, oxygen, carbon, nitrogen, sulfur, etc). Forest ecosystems contain low or null levels of pollutants in the air, soil and water. Forest environments represent self-regulating systems that have not been altered or manipulated by human exploitation. In consequence, in forest ecosystems, non-human life is appropriately represented by native flora and fauna.

Absorption would be the appropriate term to describe the movement of organic substrates, inorganic ions, vitamins, and water flowing from the epithelium to the interstitial fluid of the digestive tract. The action is a significant digestive process because the absorbed substance would be distributed to the cells via the bloodstream.

spin [16.1K]

The powerhouse of the cell: That is a term used to describe the MITOCHONDRIA, because its main function it to produce energy for cellular activities.

Mitochondria is the host of cellular respiration. This is where the Mitochondria take in glucose and oxygen to produce energy and is distributed all throughout the body as energy-rich molecules of ATP.

Answer:

Cellular Respiration

As you all know, cellular respiration is one of the, if not the, most important process that goes on in our bodies and other animals' bodies today. Cellular respiration is the process that is opposite from photosynthesis. While plants are taking in carbon dioxide and water to make sugar and oxygen, cellular respiration uses the oxygen and sugar o make carbon dioxide, water and 36 ATP. The three "mini processes" that take place during cellular respiration are glycolysis, oxidative respiration, and the electron transport chain. Fermentation also occurs in some cases where there is no oxygen present.

Glycolysis is the first stage in cellular respiration. It starts with a six-carbon glucose. Then, two ATP come and are converted to two ADP and two phosphates. Those same phosphates are added to the glucose to make a six-carbon glucose phosphate. That is then divided into two 3-carbon sugar phosphates. ADP comes and leaves charged as ATP because of the phosphate. Without the phosphates the process finishes with two 3-carbon piruvates.

If there is no oxygen present after glycolysis, then the next process is fermentation. Fermentation takes the 3-carbon piruvates from glycolysis and adds and electron to them. The result is lactic acid in animals and ethyl alcohol and carbon dioxide from plants, yeast and fungi. Oxygen can then be added back to the lactic acid to form piruvate again.

After glycolysis or after the oxygen is added back to lactic acid from fermentation, the oxidative respiration, also known as the Krebs cycle, takes place. The 3-carbon piruvates are converted to acetyl-CoA. That is then turned into a 6-carbon citrate. After an electron is added to NAD+ to turn it into NADH, a 5-carbon molecule is formed. Then it turns into a 4-carbon molecule which is then recycled.

The electron transport chain is occurring the whole time that cellular respiration is taking place. It starts with a NADH and a FADH2. Electrons and hydrogen ions are added until the final results are NAD and 2H which yields 32ATP and turns O2 into H2O.

Over all there is 2ATP made during glycolysis, 2ATP made during Krebs cycle, and 32ATP made during the electron transport chain for a grand total of 36ATP!!! After all these products are made they are then converted back by photosynthesis and the cycle goes on and on and on.
