How do nitrogen fixing bacteria help cycle nitrogen through ecosystem?
Nitrogen-fixing bacteria help cycle nitrogen through the ecosystems in a variety of ways. With plants, the nitrogen-fixing bacteria help ensure that nitrogen is cycled back into the soil.
What is the diffrence between fixed nitrogen and free nitrogen?
OK well free nitrogen is fixed by bacteria that live in the soil. some bacteria live in nodules, or bumps , on certain plant roots. the bacteria get food from the plants, and plants absorb fixed nitrogen from the bacteria. animals get nitrogen by eating plants or by eating prey that have eaten plants. fixed nitrogen may enter the soil in other ways too. a small amount of free nitrogen in the air by lighting. it is carried to the ground by rainfall. fixed nitrogen also enters the soil because of decomposers. decomposers break down dead organisms, and fixed nitrogen is released in the soil. the fixed nitrogen can be absorbed by plant roots.
What are the three main ways ecosystems can be altered?
directly hunting, which can cause extinctiondirectly disrupting habitatsintroducing exotic species to new habitats
How do thunderstorms help in converting nitrogen to nitrates?
The short answer is yes. I am not sure about the amount but there are only two ways nature converts N2 into a form of nitrogen that is usable by plants. The two ways are microorganisms and lightning. I believe bacteria are the main nitrogen fixers, but there might also be some algae that convert nitrogen as well. We have also mastered fixing N2, the process is the Haber- Bosh process.
What four ways that fungi are ecologically important?
1) They are major decomposers in most ecosystems 2) Responsible for nutrient cycling 3) Degrade organic matter to ingorganic matter 4) Critical part of biogeochemical cycles
What are the two ways nitrogen can be fixed?
Bacteria and Lighting
What is the need of fixing atmospheric nitrogen find out the various ways by which atmospheric nitrogen is fixed?
Why does atmospheric nitrogen need to be converted?
what are the major ways in which organisms in the ecosystems interact?
Competition, symbiosis, and predation

Nitrogen-fixing bacteria help cycle nitrogen through the ecosystems in a variety of ways. With plants, the nitrogen-fixing bacteria help ensure that nitrogen is cycled back into the soil.
What are three ways for nitrogen to be fixed?
1) Lightning 2) Biological 3) Bacteria

What two ways humans impact the nitrogen cycle?
Humans impact the nitrogen cycle by making fertilizers and burning fossil fuels, which alter the amount of fixed nitrogen our ecosystems.
What is nitrogen changed into before being used by living things?
lightning & bacterial action (nitrogen fixers).
What are the three main ways ecosystems can be altered?
directly hunting, which can cause extinctiondirectly disrupting habitatsintroducing exotic species to new habitats
What are two ways that nitrogen is fixed so plants can use it?
The only forms of nitrogen compounds that living things can make use of are ammonia compounds and nitrate compounds.These are called "fixed nitrogen". Animals obtain the nitrogen they need from proteins in the plants and/or animals they eat. Proteins are amino acid polymers and amino acids are built around an ammonia group.
In what ways do humans affect ecosystems?
we affect the ecosystem by pollution
