Cyanobacteria can affix atmospheric nitrogen (N2).
Flowering plants obtain nitrogen from the soil primarily through their roots in the form of nitrate (NO3-) and ammonium (NH4+), which are produced by the decomposition of organic matter and the activity of nitrogen-fixing bacteria. These bacteria convert atmospheric nitrogen into forms that plants can absorb. Additionally, some plants, particularly legumes, form symbiotic relationships with nitrogen-fixing bacteria in their root nodules, enabling them to directly utilize atmospheric nitrogen. This process is essential for plant growth and development, as nitrogen is a key component of proteins and nucleic acids.
Nitrogen-Fixing bacteria. aka Rhizobium
Most of the nitrogen that bacteria use comes from the atmosphere in the form of nitrogen gas (N2). Some bacteria, known as nitrogen-fixing bacteria, have the ability to convert atmospheric nitrogen into a form that can be used by other organisms, such as ammonia or nitrate.
Bacteria return nitrogen to the soil through a process called nitrogen fixation, where they convert atmospheric nitrogen into a form that plants can use. This allows plants to obtain the necessary nitrogen for their growth and, in turn, enriches the soil with nutrients.
Bacteria in soil obtain their nitrogen primarily from organic matter, such as dead plants and animals. They can also obtain nitrogen through nitrogen fixation, a process where certain bacteria convert atmospheric nitrogen into a form that plants can use.
Bacteria in the soil obtain nitrogen from various sources, such as organic matter, atmospheric nitrogen (N2), and nitrogen-fixing plants. Some bacteria can convert atmospheric nitrogen into a form that plants can use, while others break down organic matter to access nitrogen.
Cyanobacteria can affix atmospheric nitrogen (N2).
Plants obtain nitrogen from the soil in the form of nitrates and ammonium. They use nitrogen to help with their growth and development, particularly in producing proteins and chlorophyll. Some plants have symbiotic relationships with nitrogen-fixing bacteria that help convert atmospheric nitrogen into a usable form for the plants.
Photosynthesis is not a pathway by which plants obtain nitrogen in a usable form. Plants use nitrogen from the soil in the form of nitrate or ammonium through processes like nitrogen fixation by bacteria, absorption by roots, and uptake through mycorrhizal fungi.
Plants obtain nitrogen mainly from the soil in the form of nitrates or ammonium ions. During the nitrogen cycle, nitrogen-fixing bacteria in the soil convert atmospheric nitrogen into a usable form for plants. Some plants also have symbiotic relationships with nitrogen-fixing bacteria in their root nodules to help them absorb nitrogen.
Plants do not actually get their nitrogen from the atmosphere. They get it in compounds in the soil through their roots. Some plants form symbiotic relationships with bacteria in the soil. The bacteria draw nitrogen from the air and form nitrogen compounds. The plants can then use the nitrogen.
Producers obtain the nitrogen they need from the soil through their roots, where they absorb nitrogen in the form of nitrates or ammonium. Some plants have a symbiotic relationship with nitrogen-fixing bacteria, which convert atmospheric nitrogen into a form that plants can use. Additionally, some producers can directly absorb nitrogen from decomposing organic matter.

Nitrogen gas is changed into a useful form for plants by nitrogen-fixing bacteria in the soil. These bacteria convert nitrogen gas into a form that plants can absorb and use to grow, known as ammonium or nitrate.
