Give two examples of how nitrogen cycles from the abiotic portion of the environment into living things and back?
Nitrogen can enter living organisms through nitrogen-fixing bacteria in the soil that convert atmospheric nitrogen into a form that plants can use for growth. This nitrogen is then passed through the food chain as animals consume plants. When living organisms die and decompose, nitrogen is released back into the soil as ammonia by decomposers like bacteria and fungi. This ammonia can then be converted into nitrates by nitrifying bacteria, making it available for uptake by plants to continue the nitrogen cycle.
How does nitrogen fixation play a crucial role in the nitrogen cycle?
Nitrogen fixation is important in the nitrogen cycle because it converts atmospheric nitrogen gas into a form that plants can use to grow. This process is carried out by certain bacteria and other organisms, making nitrogen available for plants to take up and use for their growth and development. This helps to maintain the balance of nitrogen in the environment and supports the growth of plants, which are essential for the food chain.
What happens during the process of nitrogen fixation and how does it contribute to the overall nitrogen cycle"?
During nitrogen fixation, certain bacteria convert atmospheric nitrogen into a form that plants can use, like ammonia. This process helps make nitrogen available for plant growth, which then enters the food chain as animals consume plants. Overall, nitrogen fixation is essential for maintaining the balance of nitrogen in ecosystems and supporting plant growth.
In the nitrogen cycle, how does nitrogen fixation contribute to the overall process?
Nitrogen fixation is a crucial step in the nitrogen cycle as it converts atmospheric nitrogen into a form that plants can use to grow. This process is carried out by certain bacteria and other organisms, making nitrogen available for plants to absorb and incorporate into their tissues. This ultimately helps sustain the entire ecosystem by providing essential nutrients for plant growth, which in turn supports the food chain.
How does atmospheric nitrogen enter the soil?
Atmospheric nitrogen can enter the soil through a process called nitrogen fixation, where certain bacteria convert nitrogen gas from the air into a form that plants can use. This can occur naturally through biological processes or through human activities such as the use of nitrogen-based fertilizers.
How did DDT enter the food chain?
DDT entered the food chain because it was in the water of the fish that bald eagles ate.
How do animal commonly get nitrogen?
Through ingestion. Plants associate with thingies that live in the soil and give them nitrogen, that nitrogen goes up the food chain.
How does the nitrogen get to carivores?
Nitrogen enters the food chain primarily through plants, which absorb it from the soil in the form of nitrates. Herbivores consume these plants, assimilating the nitrogen into their bodies. When carnivores eat herbivores, they obtain the nitrogen stored in the herbivores' tissues, allowing it to continue up the food chain. This transfer of nitrogen is essential for the growth and maintenance of proteins and nucleic acids in all living organisms.
How the nitrogen cycle help the man and animals?
nitrogen cycle helps man in the balancing of relation between animals and plants and food chain
Does nitrogen exist in food chain?
Yes, nitrogen exists in the food chain, primarily as a vital nutrient for plants. It is absorbed from the soil in the form of nitrates and ammonium, which plants then utilize to synthesize amino acids and proteins. Herbivores consume these plants, incorporating nitrogen into their bodies, and subsequently, carnivores obtain nitrogen by eating herbivores. This cyclical process highlights nitrogen's essential role in supporting life across different trophic levels.
How does nitrogen enter a food web?
Nitrogen enters a food web through the process of nitrogen fixation, where certain bacteria convert atmospheric nitrogen into a form that plants can absorb. Plants then take up this nitrogen through their roots, and it is passed through the food web as animals consume plants and other animals. When organisms die and decompose, nitrogen is released back into the soil for plants to utilize again.
What correctly explains how atmospheric nitrogen is converted to nitrogen compounds used by living organisms?
Atmospheric nitrogen (N₂) is converted into nitrogen compounds through a process known as nitrogen fixation. This can occur naturally via lightning or through biological means, primarily by certain bacteria and archaea that possess the enzyme nitrogenase. These microorganisms convert N₂ into ammonia (NH₃), which can then be further processed by other bacteria into nitrites (NO₂⁻) and nitrates (NO₃⁻), forms that plants can assimilate. Ultimately, these nitrogen compounds are taken up by plants and enter the food chain, making nitrogen available to living organisms.
How is nitrogen removed from and returned to the atmosphere?
Nitrogen is removed from the atmosphere primarily through a process called nitrogen fixation, where certain bacteria convert atmospheric nitrogen (N₂) into ammonia (NH₃), which can be utilized by plants. This ammonia can further be transformed into nitrates and nitrites through nitrification, allowing it to enter the food chain. Nitrogen is returned to the atmosphere through denitrification, where bacteria convert nitrates back into N₂ gas, completing the nitrogen cycle. Additionally, processes like combustion and industrial activities can also contribute to the release of nitrogen compounds back into the atmosphere.
What is released by the weathering of rocks that can be taken up by plant roots and enter the food chain?
The weathering of rocks releases essential nutrients and minerals, such as nitrogen, phosphorus, and potassium, as well as trace elements like iron and magnesium. These nutrients are absorbed by plant roots and incorporated into plant tissues. As plants are consumed by herbivores and subsequently by carnivores, these nutrients enter the food chain, supporting various forms of life. Thus, weathering plays a crucial role in nutrient cycling within ecosystems.
An organisms trophic level is a measure of its ability to release nitrogen into the atmosphere?
No, Trophic level is the level it is in in the food chain depending on its habitat.
What food chain or food chain does a greman sheperds fit into?
If you have a seeing eye dog almost all restaurants pr food stores will allow the dog to enter. If you do not, then no restaurant or food store will allow a dog inside. No, the german shepard fits in to a domestique food chain.
How does nitrogen fixation make nitrogen available to organisms?
Nitrogen gas composes 70% of the atmosphere but because it is so stable it remains a gas and unusable to plant. Bacteria have evolved that can break the N2 bond and provide nitrogen as a soluble product to the roots of plants. Once taken up by the plant the nitrogen moves through the food chain to animals etc.
