They absorb nitrogen from the air. Then nitrogen-fixing bacteria convert it to a useable form.

How do legumes play a role in the nitrogen cycle?
Legumes play a crucial role in the nitrogen cycle by hosting nitrogen-fixing bacteria in their root nodules. These bacteria convert atmospheric nitrogen into a form that plants can use, enriching the soil with nitrogen and promoting plant growth.
What are the nutrients cycles that play especially prominent roles in the biosphere?
A. Carbon cycle B. Nitrogen cycle C. Phosphorus cycle
How does the legumes impact the nitrogen cycle?
Legumes play a crucial role in the nitrogen cycle through a process called nitrogen fixation. They host symbiotic bacteria, such as Rhizobium, in their root nodules, which convert atmospheric nitrogen into ammonia, a form that plants can use. This natural fertilization enhances soil fertility, reducing the need for synthetic fertilizers. Additionally, when legumes decompose or are incorporated into the soil, they release nitrogen, further enriching the soil and benefiting subsequent crops.
What roles do decomposers play in nitrogen cycle?
Decomposers break down the corpses and wastes of organisms and release the Nitrogen they contain as ammonia. This is called "Ammonification."
What are the three nutrient cycles that play especially prominent roles?
The three nutrients cycle that plays a big part in our ecosystem are carbon cycles, nitrogen cycles and phosphorus cycles. These three are essential to sustain life and balance in our ecosystem.
Who runs the nitrogen cycle?
The nitrogen cycle is driven by various microorganisms such as bacteria and archaea. These microorganisms play key roles in nitrogen fixation, nitrification, denitrification, and ammonification processes, which are essential for cycling nitrogen through the environment.
What is the most important organism in the nitrogen cycle?
Bacteria are the most important organisms in the nitrogen cycle. They play key roles in converting nitrogen in the atmosphere into forms that plants can use, and also in breaking down organic matter to release nitrogen back into the environment.
What are 3 things that remove nitrogen directly from the atmosphere?
Three processes that remove nitrogen directly from the atmosphere include nitrogen fixation, where certain bacteria and legumes convert atmospheric nitrogen (N₂) into ammonia (NH₃); lightning, which causes nitrogen gas to react with oxygen, forming nitrogen oxides that can eventually be deposited in the soil; and industrial processes, such as the Haber-Bosch process, which synthesizes ammonia from atmospheric nitrogen for fertilizers. These processes play crucial roles in the nitrogen cycle, making nitrogen available for biological use.
Does bacteria have a direct role in the nitrogen cycle?
Yes, bacteria play a crucial role in the nitrogen cycle. They are involved in processes such as nitrogen fixation, nitrification, and denitrification, which are essential for converting nitrogen into forms that plants can use and then back into atmospheric nitrogen.
What organisms play a role in the nitrogen cycle?
Producers (incorporate it into organic) and bacteria play a major role in the nitrogen cycle.
What are the three cycles that move through the ecosystem?
The three cycles that move through the ecosystem are the water cycle, carbon cycle, and nitrogen cycle. These cycles play crucial roles in maintaining the balance of nutrients and resources within the ecosystem, ensuring the survival of organisms and the functioning of ecosystems.
Which organisims help convert gaseous nitrogen into ammonia in the nitrogen cycle?
In the nitrogen cycle, nitrogen-fixing bacteria play a crucial role in converting gaseous nitrogen (N₂) into ammonia (NH₃). These bacteria, such as Rhizobium, live in the root nodules of legumes or in the soil, where they convert atmospheric nitrogen into a form that plants can use. Additionally, some free-living bacteria, like Azotobacter, also perform this nitrogen fixation in the soil. This process is essential for replenishing the nitrogen available to plants and, consequently, the entire ecosystem.
