What do organisms rely on to get the nitrogen they need?
Organisms rely on various sources to obtain the nitrogen they need, primarily through the nitrogen cycle. Plants absorb nitrogen from the soil in the form of nitrates and ammonium, which are produced by the decomposition of organic matter and the activity of nitrogen-fixing bacteria. Animals, in turn, acquire nitrogen by consuming plants or other animals. Additionally, some bacteria can convert atmospheric nitrogen into forms usable by living organisms through a process called nitrogen fixation.
How is nitrogen transferred from atmosphere to plants?
Nitrogen gas in the atmosphere is taken up by certain soil bacteria, called nitrogen-fixing bacteria, which convert it into a form that plants can use, such as ammonia. Plants then absorb this nitrogen from the soil through their roots and use it to make proteins and other essential molecules. Some plants, like legumes, have a symbiotic relationship with nitrogen-fixing bacteria, while others rely on nitrogen from decaying organic matter or nitrogen-containing fertilizers.
Can all living thins absorb nitrogen directly from the atmosphere?
No, not all living things can absorb nitrogen directly from the atmosphere. Most organisms, including plants and animals, rely on nitrogen-fixing bacteria to convert atmospheric nitrogen into forms they can use, such as ammonia or nitrates. Certain plants, particularly legumes, have symbiotic relationships with these bacteria that enable them to access nitrogen. However, the majority of life forms must obtain nitrogen through the food chain or soil.
How do bacteria help plants to get nitrate?
Nitrogen- fixing bacteria consume nitrogen in the air and change it into a for that plants can use.
Why is nitrogen gas in the atmosphere useless to plants?
Plants cannot use nitrogen gas directly because they lack the necessary enzymes to convert atmospheric nitrogen gas (N2) into a usable form like ammonia (NH3) or nitrate (NO3-). Instead, plants rely on specialized bacteria in the soil called nitrogen-fixing bacteria to convert atmospheric nitrogen into a form that plants can use for growth.
Why cant plants absorb gaseous nitrogen?
plants and animals are not adapted to absorb nitrogen from the air. Nitrogen Fixation is a process where nitrogen is changed into a more reactive form for plants and animals to use. There are several ways where nitrogen fixation can happen: lightning, bacteria, carnivorous plants and industrial fixation.
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.
Why do plants rely on animals?
to keep them alive hehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehehe
How do the nitrogen and oxygen cycles make plants and animals interdependent?
The nitrogen and oxygen cycles create interdependence between plants and animals through their roles in essential biological processes. Plants absorb nitrogen from the soil, which they use to create proteins and nucleic acids, while they also produce oxygen as a byproduct of photosynthesis. Animals rely on plants for oxygen to breathe and for nutrients when they consume plant matter. This exchange ensures that both plants and animals thrive in their ecosystems, highlighting their interconnectedness.
Am infectious agent smaller than bacteria and capable of ifecting almost all plants and animals is a?
virus. Viruses are small infectious agents that can infect a wide range of hosts, including plants and animals. They are smaller than bacteria and rely on host cells to replicate and cause infections.
Why cannot green plants absorve gasious nitrogen?
green plants do not have the "power" to break the triple bond of N2 molecule. in better words, they do not have suitable enzymes. on the other hand, some bacteria have, the so colled "nitrogen fixing bacteria", living on legume plant roots.
Why must carnivorous plants rely on insects for their source of nitrogen?
Carnivorous plants must rely on insects for nitrogen since they are found in soils with low nitrogen levels. Since the soil can't provide them with enough nitrogen, they must consume insects to meet their nitrogen requirements.
