What might happen in community if all the nitrogen fixing bacteria died?
organisms in in the community would get sick or die
Assume that transgenic organisms can be develop to speed nitrogen fixation how might use of these organisms affect an ecosystem?
If these transgenic organisms hastens the process of nitrogen fixation then the nitrogen cycle in general is sped up as a result. Ultimately, fixated nitrogen aids in plant growth since it helps fertilize the soil. It helps improve the soil's organic content and volume. This leads to various effects, good and bad. For one thing, farmers can use the organisms for better quality of crops and faster production. On the other hand, an imbalance in the earth's atmosphere can also be triggered and a lot of organisms like bacteria and ultimately us humans will be affected. Some species who had no problem surviving otherwise will die out while others will thrive and find it conducive to their existence.
How do living organisms obtain their nitrogen requirement?
All organisms need nitrogen to live and grow. Plants take up nitrate ions from the soil, they are then absorbed into roots by active transport, the plant then produces nitrogen-containing compounds such as protein. This nitrogen then gets into the food web as primary consumers feed on plants and obtain the nitrogen-containing compounds. However, the atmosphere is made up of 78% nitrogen and is unavailable in this form to organisms. This is due to the triple bond between the two N atoms causing it to be inert. To be used by organisms, it must be converted to a chemically available form, such as ammonium (NH4+), nitrate (NO3-), or urea ((NH3)2CO). There are five main processes that convert nitrogen to a more accessible form. They are; nitrogen fixation, nitrogen uptake, decay process, nitrification and denitrification. The first process I will talk about is nitrogen fixation. There, the nitrogen is converted to ammonium; it is the only way organisms can obtain nitrogen directly from the atmosphere. The only organism that can fix nitrogen through metabolic process is bacteria from the genus Rhizobium. The nitrogen fixers are usually found on host plants, but there are also nitrogen fixing bacteria found without host plants. They are known as free-living nitrogen fixers, e.g. in the aquatic environment a very important nitrogen fixer would be cyanobacteria. Nitrogen fixation can also be carried out in high-energy natural events, such as lightning and forest fires. The high-energy breaks the triple bond between the two nitrogen atoms producing a significant amount of single nitrogen atoms available for use. The next process is nitrogen uptake, this is where plants or bacteria itself makes use of the ammonia produced by the nitrogen fixing bacteria. The ammonium is converted from NH4+ to N to make protein or other nitrogen containing compounds. A very important process that returns nitrogen back to the nitrogen cycle for use is the decay process. When organisms, die, nitrogen is converted back into inorganic nitrogen by a process called nitrogen mineralization. Decomposers consume the organic matter and this leads to decomposition. Nitrogen contained within the dead organism in converted to ammonium, it is then available for use to plants, or transformed into NO3- (nitrification). Through the nitrogen cycle, food-making organisms obtain necessary nitrogen through nitrogen fixation and nitrification. Nitrogen compounds are returned to atmosphere and soil through decay and denitrification. In crops, few plants are left to decay back into soil, so the nitrogen cycle doesn't supply enough nitrogen to support plant growth. Therefore natural or artificial fertilizers containing NO3- or NH4+ compounds are added.
What organisms are most fragile with loss of oxygen?
Animals because they will die within minutes of having no oxygen.
How will a chemical spill most likely affect the grass area?
The grass will die because it will not be able to use the nitrogen compounds in the soil
If the tissues organsand organ systems were injured or diseasedwhat will happen to the organisms?
Get sick and/or die.
What happens to the organisms of tissues organs organs systems if these cells are damaged or diseased?
the organism will die.
What might happen in a community if all the nitrogen fixing bacteria died?
organisms in in the community would get sick or die
What might happen in community if all the nitrogen fixing bacteria died?
organisms in in the community would get sick or die
How lightning helpful to organisms?
Lightning is helpful to organisms because it provides nitrogen, which plants need a little to live. Other organisms, such as animals, not so good for because it good die if it is un-sheltered.
Why is nitrogen an essential for living organism?
Nitrogen is essential for living organisms because it helps plants grow, and plants supply animals their food. And without plants we would die.
Give two examples of how nitrogen cycles from the abiotic portion of the environment into living things and back?
when an animal urinates nitrogen returns to the water or soil,and when organisms die and decay,nitrogen returns to the soil and eventually to the atmosphere
How does nitrogen get from organisms back into the atmosphere?
Nitrogen used by plants and animals is returned to the atmosphere by the action of bacteria. Bacteria break down proteins to obtain energy, releasing nitrogen back into the air in the process.
What would happen if all the nitrogen fixing bacteria disappeared?
Life dependent on plants would die. The nitrogen fixing bacteria change nitrogen into a useable and they have a symbiotic relationship with plants. Plants need the nitrogen to synthesize amino acids. Without being able to synthesize amino acids, the plant would die and the other organisms dependent on it would starve/die off.
Why are nitrogen oxygen and carbon dioxide important to marine organisms?
nitrogen oxygen and carbon dioxide are important into the plants because without them there are no plants in the world and people will die cause there is no carbon dioxide
What happens to most organisms when they die?
They Decompose, or are fed on by other organisms, Mainly by decomposers.
What happens to the nitrogen when organisms die?
As the organisms decompose the nitrogen (and most other components) in the body are utilized by any organisms that eat it. Whether that is fungi, bacteria, insects, scavenging animals is arbitrary. All the materials that make up an are mainly Carbon, Hydrogen, Nitrogen and Oxygen along with an assortment of minerals all of which will be recycled in one form or another into other members of the living community. Elements are not destroyed in the process of decomposition but the complex molecules are broken down.
