Role of organisms in the nitrogen cycle:

Bacteria play a central role: Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates. Bacteria of decay, which convert decaying nitrogen waste to ammonia. Nitrifying bacteria, which convert ammonia to nitrates/nitrites.

Explanation:

I THINK THIS IS SHORT AND EASY

Plants use nitrates to create proteins. Animals eat plants for protein. Humans add nitrogen-rich fertilizers and manure to the cycle.

The process by which nitrogen is changed into a variety of different chemical forms as it cycles through different ecosystems, including the atmosphere, land, and ocean, is known as the nitrogen cycle, which is a biogeochemical cycle. Both biological and physical methods can be used to complete the transformation of nitrogen.

In order to synthesize proteins, plants must first take up nitrates from the surrounding soil. Plant material is digested by animals, which then contributes to the formation of animal protein. Both the addition of nitrogen-rich fertilizers to the soil and the utilization of manure are examples of how humans make a contribution to the cycle.

Answer:

Abiotic factors refer to non-living physical and chemical elements in the ecosystem. ... Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction.

Answer: 3 examples of relationships between abiotic and biotic factors in the ecosystem are plants use sunlight, water, and carbon dioxide to make food. Another example is the interaction between turtles and soil, some turtles are known to bury themselves in the soil. Elephants and water interact as well in order to stay hydrated elephants drink water.

Pitting edema is a result of fluid retention and is caused by proteins spilling out into the interstitial spaces of cells instead of staying in the vasculature (vessels) where they belong.

A common sign of right sided heart failure. When blood gets pumped into the right atria/ventricle it is weak and cannot pump all the blood through sufficiently so there is a back up of blood (like a traffic jam) into the rest of the body, causeing edema.

Also common in renal failure because the kidney cannot sufficiently rid the body of its excessive waste products and protein via urine (which is what healthy kidneys do).

Answer:

Given that water is clear and colorless, it seems that it will absorb very little direct radiation from the sun. The sides and the bottom of the pool can however heat it by conduction.

Explanation:

hope it help and if it doesnt sorry;)

Answer:radiation

Explanation:It’s radiation because when you conduct heat to something it mostly to an object and that is creating energy.Conduction is also mostly used with a object like wood doesn’t conduct heat well but metal does.

Answer:

mantle

Explanation:

The mantle is very thick: 1800 miles deep. The mantle is a little bit like a sandwich. On the top and bottom parts of the mantle, the rock doesn’t move very much. In the middle of the mantle is the asthenosphere. This part of the mantle moves around fairly slowly. This moving mantle layer pushes the earth’s plates around.

Answer:

Minerals can be identified by their physical characteristics. The physical properties of minerals are related to their chemical composition and bonding. Some characteristics, such as a mineral's hardness, are more useful for mineral identification.

Explanation:

Answer:

1. Hardness, the ability to resist being scratched—or hardness—is one of the most useful properties for identifying minerals. (ex. diamond)

2. Luster, luster is how a mineral reflects light.

3. Color, one of the most obvious properties of a mineral is color. (ex. Red- Ruby, Green- Jade, Blue- Opal)

4. Streak, the color of a mineral in its powdered form. It is usually obtained by rubbing the mineral on a hard, white surface, such as a tile of un-glazed porcelain, so as to yield a line, or streak, of fine powder. (Kinda like rubbing chalk on a concrete floor to get the color)

5. Specific Gravity, the weight (How heavy is it?)

lactobacillus is responsible for producing lactic scid. It is broken down in two groups, hermofermentative species and hetorfermentative species.

The anaerobic condition forms lactic acid in muscle tissue. In the absence of oxygen, glucose cannot enter the Krebs cycle and enter fermentation. This is called lactic acid fermentation.

The cell takes the glucose for glycolysis. In the glycolysis process, the glucose is broken down into pyruvate. For this glycolysis process, oxygen is not required.

In the absence of oxygen, pyruvate is used for fermentation. There are two types of fermentation: alcoholic fermentation and lactic acid fermentation. when a person runs too fast and, as a result, can't breathe properly. Due to these, the cell cannot get enough oxygen.

As oxygen is absent, the muscle cell continues the lactic acid fermentation. The lactic acid makes the blood acidic. During alcohol fermentation, pyruvate is converted into ethanol. Apart from this bacteria such as lactobacillus make lactic acid.

Hence, in the process of lactic acid fermentation, lactic acid is produced by the cell in the absence of oxygen.

Answer:

Nitrates and phosphates lead to eutrophication and anoxia in the creek which caused aquatic animals to die and damaged the creek.

Explanation:

Nitrates (NO3-) are chemical compounds that contain nitrogen and oxygen molecules. They are salts that are commonly found in fertilizers and are soluble in water. Phosphates are also compounds that are used in agricultural processes.

Nitrates and phosphate found in water are usually from plants that  have been washed off by rain water and also from vehicles' exhaust.

When there are abnormally high levels of nitrates and phosphates in water, it becomes difficult for aquatic animals to survive. In bodies of water, the nitrates and phosphates become sources of food to algae and other plants, this causes them to become over stimulated, and lead to Eutrophication (a high concentration of nutrients) and Anoxia (lack of oxygen).

This causes the fishes to run out of oxygen and die. Then the water begins to change color (milky white or green), give off an offensive odor and gradually turns into a  swamp and eventually a meadow
