Describe the nitrogen cycle and explain why it is important for the survival?
The nitrogen cycle is the process by which nitrogen is converted between different chemical forms in the environment. This cycle is crucial because nitrogen is an essential element for the growth of plants and the production of proteins in living organisms. The cycling of nitrogen ensures that it is available in a usable form for plants and other organisms, ultimately contributing to the balance of ecosystems and the overall health of the environment.
How are nitrogen and bacteria and plants all related to each other?
some leguminous plants like peas have legumes in there roots. legumes are small swellings, which contains nitrogen fixing bacteria. they helps in nitrogen fixation. other plants like paddy can use these nitrogen for there growth.
What is the only way that animals can obtain nitrogen?
Animals obtain nitrogen primarily through the consumption of plants or other animals that contain nitrogen-containing compounds, such as proteins. They break down these compounds during digestion and reuse the nitrogen to build their own proteins and other essential molecules.
What happens to the bodies of organisms after they die?
After an organism dies, its body goes through a process of decomposition, where bacteria and other organisms break down the body into simpler compounds. These compounds are then released back into the environment as nutrients, contributing to the ecosystem's nutrient cycle.
What do you called the animal that eats other animals?
prey also called carnivores. if the animal also eats plants, it's called an omnivore.----------------------------------------------------------------------------------------just leave it at 'prey' that is the simplest answerpredetors
What is the transfer of nitrogen from air to soil to organism?
Nitrogen gas in the air is converted into usable forms by soil bacteria through a process called nitrogen fixation. Plants then take up these forms of nitrogen from the soil. When organisms consume plants, they obtain nitrogen from the plants, and the nitrogen cycles through the food chain as organisms are consumed by other organisms.
What role do consumer in the nitrogen cycle?
Consumers play a role in the nitrogen cycle by obtaining nitrogen from consuming plants or other organisms. Through their waste and decomposition, they release nitrogen back into the environment for plants to use again. This helps maintain the balance of nitrogen in ecosystems.
In what form most organisms obtain nitrogen?
Most organisms obtain nitrogen in the form of nitrate (NO3-) or ammonium (NH4+). These forms of nitrogen are usually present in the soil and can be taken up by plants. Animals then obtain nitrogen by consuming plants or other animals.
Do most organisms use nitrogen in the form of nitrogen gas?
No, most organisms cannot use nitrogen gas directly. They rely on nitrogen-fixing bacteria to convert atmospheric nitrogen into a usable form such as ammonia or nitrate, which can then be absorbed by plants and other organisms.
Why are nitrogen fixing bacteria so important to other organisms?
Nitrogen fixing bacteria are important because they convert atmospheric nitrogen into a usable form (ammonia) that plants can absorb and incorporate into their tissues. This process is essential for the growth and development of plants, which serve as the base of the food chain, ultimately supporting all other organisms that rely on plants for energy and nutrients.
How do animals obtain their nitrogen requirements?
Animals obtain their nitrogen requirements primarily by consuming nitrogen-rich foods such as plant proteins or other animal tissues. The proteins in these foods are broken down into amino acids, the building blocks of proteins, which are then used by the animal to meet its nitrogen needs. Nitrogen can also be obtained indirectly by consuming microbes that can convert atmospheric nitrogen into forms that animals can use.
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.
What organisms are capable of converting gaseous nitrogen in the air into a form that other living organisms can use?
Nitrogen-fixing bacteria, such as Rhizobium and Azotobacter, are capable of converting gaseous nitrogen in the air into a form that other living organisms can use, such as ammonia or nitrate. These bacteria form symbiotic relationships with plants, providing them with usable nitrogen in exchange for carbohydrates.
Can nitrogen be directly used by living things?
No, nitrogen gas cannot be directly used by most living organisms. Instead, nitrogen-fixing bacteria in the soil or in plant roots convert atmospheric nitrogen into a form (ammonia or nitrates) that can be used by plants to make proteins. Other organisms then obtain nitrogen by consuming these plants.
Do most organisms use nitrogen directly form air?
Since the air around you is about 78% nitrogen gas, you might think it would be easy for organisms to retrieve nitrogen easily. However, most organisms cannot use nitrogen gas. Nitrogen gas is called "free" nitrogen because it's not combined with other atoms. Most organisms can use nitrogen only when it has been combined with other elements to form nitrogen-containing compounds. So, is that the answer you were looking for (possibly for homework)?
Can most organisms use the free nitrogen in air?
No, most organisms cannot use the free nitrogen in the air. Instead, certain bacteria and archaea have the ability to convert atmospheric nitrogen into a form that plants can use through a process called nitrogen fixation. This fixed nitrogen then moves through the food chain as organisms consume plants and other organisms.
How does Nitrogen from the Atmosphere the Abiotic part of the ecosystem Converted in to the biotic part of the ecosystem In Organisms?
By lightening and by nitrogen fixing bacteria in the roots of certain plants (eg the legumes).
