Which chemical cycle involves the process of photosynthesis?
it is not nitrogen cycle
Why are bacteria the most important part of the nitrogen cycle?
The conversion of ammonia to nitrate (nitrification) is performed primarily by soil-living bacteria and other nitrifying bacteria. It is important for the ammonia to be converted to nitrates because accumulated nitrites are toxic to plant life. Denitrification is the reduction of nitrates back into the largely inert nitrogen gas (N2), completing the nitrogen cycle.
What process is not part of the nitrogen cycle?
it is provised
Why is the nitrogen cycle important?
They breakdown and recycle complex proteins and other materials. Without it, dead things would not decay and return to the earth. (As my friend put it - without the nitrogen cycle the earth would be clogged up with dead things)
What is the purpose of nitrogen-fixing bacteria?
Although the air is made up of about 70% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle Updated by: Levi Levitt
What is a plant's role in the nitrogen cycle?
Plants consume nitrogen in the form of Nitrates. Nitrogen gets converted into nitrates by the denitrifying bacteria. These plants absorb nitrogen in the form of nitrates through the groundwater.
What role does a animal in a nitrogen cycle?
They eat the plants that absorb the nitrates.
The conversion of nitrates to nitrogen gas by bacteria is called?
Nitrogen Fixation.
The conversion of nitrates back into free nitrogen by bacteria in the soil is?
nitrogen cycle
The conversion of nitrates present in the soil or water to free molecular salts to nitrates?
nitrogen cycle
What would happen if the bacteria that cause denitrification were removed from the nitrogen cycle?
denitrification is soil bacteria converting nitrates into nitrogen gas, is process releases nitrogen into the atmosphere. If there wasn't any bacteria, there would be no process and therefor the nitrogen wouldn't make it into the atmosphere.
The steps of the nitrogen cycle?
A deer in the woods has just released urine. Number the steps to follow the nitrogen molecules in the urine as they go through the nitrogen cycle.To get you started, Step 1 is "Nitrogen is found in urine, which gets broken down into ammonium through the process of ammonification."1.Step 1Bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium.2.Step 2Ammonium can be absorbed by plants, but some is converted into nitrates, which are better for plants to absorb. This is called nitrification.3.Step 3Nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification.4.Step 4The deer eats the plants and uses the nitrogen-containing proteins for cell growth.5.Step 5Some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere.6.Step 6Plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
What do nitrates and organic matter produce?
Nitrogen gas becomes the ultimate product of nitrates and organic matter and complete the nitrogen cycle. Organic matter converts into ammonium, which oxidizes into ammonia and then into nitrites. Nitrites oxidize into nitrates, which reduce into nitrogen gas.
What will happen if nitrogen fixation does not take place?
if nitrogen fixation does not take place nitrates will not be taken if nitrates are not there so there is no photosynthesis so it metaboills and if photosynthesis is not there so there is no life thats what nitrogen fixation not allows in nitrogen cycle
What does nitrogen in nitrates do to plants?
Nitrates help regenerate and help build the glucose in the plant. The plant uses the nitrogen cycle to help absorb sunlight in a process called photosynthesis. To get on a chemical level, the DNA in a plant's cellular reproduction attaches to cellular bases. Their are four bases on RNA and DNA: Adenosine, Thyosine, Cenosine, and Genosine. Adenosine attaches to thyosine, and Cenosine attaches to Genosine. It repeats this cycle and creates a long twisty ladder called DeoxiyiboNucleicAcid (DNA) The DNA becomes saturated by and helps the plant absorb sunlight in Photosynthesis.
Why is it important for nitrogen to be recycled in an ecosystem?
Nitrogen is one of the elements present in nitrates which is a mineral that plants need for growth. Nitrogen fixing soil bacteria take the nitrogen from the air and change it into ammonium, and then further changed by nitrifying bacteria into nitrates. these nitrates are then taken up by the plants.
