How can cyanobacteria in contrast to saprotrophic bacteria live in environment that lacks organic nutrients?
Cyanobacteria is able to live in an environment as it is photosynthetic and can utilize nitrogen from the air.
Bacteria return nitrogen to the soil by which process?
The role of bacteria in the Nitrogen Cycle is to perform biological nitrogen fixation. This process is an important part of the Nitrogen Cycle because it converts oxygen into ammonia that plants are then able to use.
What is the need of nitrogen in atmosphere?
What does it mean to say the "need of nitrogen in the atmosphere"? Needed for who, for what? Nitrogen is in the atmosphere regardless of who needs it.Is the nitrogen gas used for something? Definitely. Certain organisms are able to convert nitrogen gas, N2, in the atmosphere into NH3, ammonia, which is used as a plant nutrient. This is generally called nitrogen fixation.
What is the symbolic relationship found between plants and nitrogen fixing bacteria?
Nitrogen is vital to plants (as well as all other life) as it is a key component of chlorophyll, proteins, and DNA. Without nitrogen fixing bacteria, most plants would quickly deplete the limited stores of nitrogen found in the soil in their immediate area. Nitrogen fixing bacteria are able to synthesize ammonia from free nitrogen in the air, and plants can utilize this ammonia in all of their biological processes.
What is in the Phylum Cyanobacteria?
Cyanobacteria are prokaryotic bacteria.they are able to fix Nitrogen.they produce oxygen as bi-product.
What is an example of a nitrogen-fixation bacterium?
Nitrification can occur in drinking water. In water distribution systems where chloramines are used as the secondary disinfectant, the presence of free ammonia can sometimes act as a substrate for ammonia-oxidizing microorganisms. The subsequent reactions can lead to the depletion of the disinfectant residual in the system.
Does most nitrogen fixation use the energy released by lighting?
Nitrogen fixation is the conversion of atmospheric Nitrogen gas (N2) into Ammonia, and Nitrates that can be used by plants.Much of the nitrogen fixation is done by a symbiotic relationship between nitrogen fixing bacteria and various plants.Thus, the bacteria are not directly doing photosynthesis. The plants do the photosynthesis, and the bacteria are able to get the secondary energy from the plants and plant material.
A chemical is spilled in a grassy area. The chemical has been known to kill all bacteria that live in the soil. How will this most likely affect the area?
The flowers will not grow as well because bacteria are needed to fix nitrogen.
How do bacteria help the nitrogen cycle?
Actually nitrogen exist in the atmosphere in dinitrogen (N2) form and cannot be utilized directly. As such bacteria help in converting atmospheric nitrogen into ammonia which then can be used by the plants.
What are two effects of pigments found in cyanobacteria?
Some have a blue pigment that helps in photosynthesis. This pigment gives those cyanobacteria a blue tint. Other cyanobacteria have red pigment. Flamingos get their pink color by eating red cyanobacteria. or Cyanobacteria lives in water and these bacteria contain the green pigment chlorophyll. Chlorophyll is important to photosynthesis.
How might cyanobacteria have contributed to the evolution of animals?
Cyanobacteria were the first organisms to produce oxygen from water and carbon dioxide. When the oxygen levels increased, an ozone layer developed, which blocked excess ultraviolet light from reaching the land. This made it possible for organisms to move onto land without being killed by UV light. Additionally, the oxygen created an atmosphere that permitted aerobic organisms to evolve, and aerobic organisms were the majority of those that ended up colonizing the land.
How did cyanobacteria affect evolution process?
Cyanobacteria photosynthesised, which meant that they released oxygen. This was the key to the evolution of eukaryote cells that aerobically respired. From their evolution, the O2 levels in the atmosphere was able to increase; this is why we eventually evolved.
