Explain the role of living things such as yourself in the nitrogen cycle
Simple answer please
Answer:
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.
What is nitrogen 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.

Is The sun warms up the swimming pool conduction or radiation
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.

What role have nitrates and phosphates played in damaging Muddy Creek?
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

How are unknown minerals identified?
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)

Summarize sexual reproduction in plants. I need help please!!
Answer:
Plant reproduction is the development of new offspring that can be achieved through sexual or asexual reproduction in plants. By the fusion of gametes, sexual reproduction creates embryos, resulting in offspring genetically distinct from the parent or parents. Asexual reproduction creates new individuals, genetically similar to the parent plants, without the fusion of gametes.

Volcanos extend so deep below earth’s surface that they reach down to the next layer. Which is the second layer of earth?
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.
what is one thing you would see in a molecule that you would not see in a compound
The one thing that you would see in a molecule that you would not see in a compound is the molecular bonds.
What is a Molecule?A Molecule may be defined as the smallest particle of a substance that has all of the physical and chemical properties of that substance. Molecules are made up of one or more atoms. These atoms are held together by attractive forces known as chemical bonds.
According to the context of this question, a compound depends on how many different kinds of elements make it up. Compounds contain two or more different elements. Water is a molecule because it contains molecular bonds. While a molecule has molecular bonds that togetherly held atoms in it.
