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?
the elements ussualy fertalize plants after they have been reduced and recycled naturaly back into soil that is great for plants of all kinds. the elements of the animal are naturally recyled into soil that is great for plants of all kinds
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. They can not use nitrogen gas because the triple bonds of nitrogen can only be broken down for use in living things, plants, by the symbiotic bacteria in the root nodes. Then in other forms nitrogen is taken up into the plant and from there to other trophic levels.
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 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.
How do animals obtain their nitrogen requirements?
Nitrogen is found in all living systems as part of the makeup of biological compounds. Animals obtain the nitrogen they need by eating plants, or by eating other animals that have eaten plants.
Why is nitrogen necessary for life to thrive?
Nitrogen is necessary for life to thrive because it is a key component of proteins, DNA, and other essential molecules in living organisms. Plants and other organisms rely on nitrogen to grow and reproduce, making it crucial for the functioning of ecosystems and the overall health of living organisms.
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.
Does the nitrogen cycle start with plants, and how do they play a crucial role in this essential process"?
Yes, the nitrogen cycle starts with plants. They play a crucial role by absorbing nitrogen from the soil and converting it into a form that can be used by other organisms. This process, known as nitrogen fixation, is essential for the growth and development of all living organisms.
What is the process of nitrogen fixation in the nitrogen cycle and how does it contribute to the overall ecosystem balance?
Nitrogen fixation is the process where certain bacteria convert atmospheric nitrogen into a form that plants can use. This helps plants grow and provides essential nutrients for other organisms in the ecosystem. By contributing to the availability of nitrogen, nitrogen fixation helps maintain the balance of nutrients in the ecosystem, supporting the growth of plants and ultimately all living organisms.
