Describe the path of nitrogen through its biogeochemical cycle?
Nitrogen gas in the soil is used by plants, which are eaten by animals. The waste products of the animals contain the nitrogen. It is broken down by bacteria, which releases nitrogen gas into the atmosphere, and the cycle repeats.
What are two ways that nitrogen is fixed so plants can use it?
The only forms of nitrogen compounds that living things can make use of are ammonia compounds and nitrate compounds.These are called "fixed nitrogen". Animals obtain the nitrogen they need from proteins in the plants and/or animals they eat. Proteins are amino acid polymers and amino acids are built around an ammonia group.
How does the nitrogen cycle work to facilitate the movement of nitrogen through different ecosystems?
The nitrogen cycle is a process that moves nitrogen through different ecosystems. Nitrogen gas in the air is converted into a form that plants can use by bacteria in the soil. Plants then take up this nitrogen through their roots. When animals eat plants, they also take in nitrogen. When plants and animals die, bacteria break down their remains, releasing nitrogen back into the soil. This cycle continues, allowing nitrogen to be used by different organisms in various ecosystems.
How do animals like the deer pictured contribute to the nitrogen cycle?
Animals like deer contribute to the nitrogen cycle primarily through their waste, such as urine and feces, which contains nitrogen-rich compounds. When they excrete waste onto the soil, it can be broken down by decomposers and converted into ammonia and other forms of nitrogen that can be taken up by plants. This helps in the recycling of nitrogen in the ecosystem.
How does nitrogen fixation contribute to the nitrogen cycle?
Nitrogen fixation is the process by which certain bacteria convert atmospheric nitrogen into a form that plants can use. This helps to increase the availability of nitrogen in the soil, which is essential for plant growth. In turn, plants take up this nitrogen and incorporate it into their tissues. When plants die or are consumed by animals, the nitrogen is returned to the soil and eventually decomposed by bacteria, completing the nitrogen cycle.
Why do plants and animal and other organisms need nitrogen?
Nitrogen is required by plants and animals for protein synthesis
How do other animal the nitrogen they need?
Plants and animals die and decomposers break down their nitrogen containing molecules to ammonia. All animals get the nitrogen they need by eating plants, by eating other animals that ate plants, or by eating animals that ate animals that ate plants.
Why do animals and plants need nitrogen?
bcz
Can humans get the nitrogen they need to exist in the air?
Plants and animals die and decomposers break down their nitrogen containing molecules to ammonia. All animals get the nitrogen they need by eating plants, by eating other animals that ate plants, or by eating animals that ate animals that ate plants.
How do plants get nitrogen compared to how animals get nitrogen?
Most plants get nitrogen from fertilizers. Some plants can have a process called nitrogen fixing in which nitrogen from the is turned into ammonium compounds. Animals get their nitrogen from food, by eating plants and other animals.
What is the source of nitrogen for animals?
Animals get nitrogen from plants.
Why do animals need nitrigen to live?
Animals and plants need nitrogen to live because proteins and other biological compounds contain nitrogen. In plants, nitrogen compounds perform photosynthesis. In humans, nitrogen is the basis for amino acids, the building blocks of genetic material.
How do we get the nitrogen we need?
We get the nitrogen our bodies need by eating food.
What are two functions of plants and animals in the nitrogen?
plants and animals
Where do animals get nitrogen from?
Animals get nitrogen from the proteins found in their food. When animals consume plants, they break down the proteins into amino acids, which are then used to build new proteins in their bodies. Nitrogen is an essential component of amino acids, which are the building blocks of proteins in animals.
Why is nitrogen needed by plants and animals?
Nitrogen is essential for the synthesis of proteins, which are required for growth, development, and overall function of plants and animals. It is a key component of chlorophyll in plants, allowing them to undergo photosynthesis. In animals, nitrogen is needed for the formation of DNA, RNA, and essential amino acids.
How do plants and animals differ in the ways they obtain nitrogen?
Plants get it from bacteria which live associated with their roots who take atmospheric nitrogen and fixate it (nitrogen cycle). Animals can only get it by ingesting organic compounds which contain nitrogen, such as plants and other animals which have eaten plants.
