Benefits of lightning?
Lightning is important because it helps to balance the Earth's electrical charge, contributes to the nitrogen cycle by causing nitrogen to fix in the soil, and can trigger wildfires that play a role in maintaining ecosystems.
What organism is involve in the most nitrogen fixation earth?
Nitrogen fixation carried out by the microbes is known as biological nitrogen fixation.many microbes can fix nitrogen non-symbiotically like cyanobacteria,anabaena,etc whereas certain fix N2 symbiotically like rhizhobium species.
What types of organisms do nitrogen fixation?
nitrogen fixates the amino acids in plants such as the yershipititis yashori. it makes them grow to up to twice their size and grow large gelatinous growths called bellentigus lergenous
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.
Name the microorganisms which can fix atmospheric nitrogen in the soil?
Examples of microorganisms that can fix atmospheric nitrogen in the soil include certain species of bacteria such as Rhizobium and Azotobacter. These bacteria have the ability to convert atmospheric nitrogen into a form that plants can utilize, ultimately promoting plant growth and soil fertility.
What are the unicellular organisms that resemble a bacterial cell and are found in fresh and sea water?
The unicellular organisms that resemble bacterial cells and are found in fresh and saltwater environments are called cyanobacteria. These organisms are photosynthetic, often forming blue-green blooms in water bodies, and play important roles in aquatic ecosystems as primary producers. They are also known for their ability to fix nitrogen from the atmosphere.
Where do bacteria fix nitrogen gas?
Some bacteria fix nitrogen gas in the soil, forming a symbiotic relationship with plants by converting atmospheric nitrogen into a form that plants can use for growth. Other bacteria, like cyanobacteria, fix nitrogen gas in aquatic environments like oceans and freshwater bodies, contributing to the overall nitrogen cycle.
How algae can fix nitrogen?
Some species of algae, like blue-green algae (cyanobacteria), have the ability to fix nitrogen through a process called nitrogen fixation. They contain specialized cells called heterocysts that enable them to convert atmospheric nitrogen gas into a form that can be used by plants and other organisms. This nitrogen fixation process is important for providing essential nutrients for the growth and development of ecosystems.
How do colonies of cyanobacteria harm aquatic organisma?
Colonies of cyanobacteria can harm aquatic organisms by producing harmful algal blooms, which can deplete oxygen levels in the water, leading to fish kills. Some cyanobacteria also release toxins that can be harmful to other aquatic organisms, such as fish, shellfish, and other wildlife. Additionally, the presence of cyanobacteria can alter water clarity and nutrient levels, disrupting the ecosystem balance.
What are the characteristics of nostoc?
Nostoc is a genus of cyanobacteria that form colonies of gelatinous masses. They have the ability to fix nitrogen from the atmosphere and play a crucial role in nitrogen cycling in aquatic ecosystems. Nostoc colonies are usually greenish-blue in color and can be found in various habitats such as soil, rocks, and freshwater.
Rhizobium?
have a mutually beneficial relationship with plants -> Organisms fix nitrogen that is used for a nutrient source for the plant
A certain essential element is not usable to organisms in its free state special bacteria can fix it into a form that is usable the element is?
nitrogen
What is the ISBN of The Nitrogen Fix?
The ISBN of The Nitrogen Fix is 0-441-58117-X.
How many pages does The Nitrogen Fix have?
The Nitrogen Fix has 289 pages.
When was The Nitrogen Fix created?
The Nitrogen Fix was created in 1980-09.
What is an anabaena?
Anabaena is a biological term used to describe a genus of cyanobacteria that is found as plankton. They can form symbiotic relationships with certain plants, and is known for it's nitrogen fixing abilities.
How do water plants obtain nitrogen if it is insoluble in water?
Marine ecosystems: Nitrogen is fixed in the photic zone by cyanobacteria who acquire it from the atmosphere (it isn't completely insoluble). The fixed Nitrogen can enter the water as Ammonia or Urea (which is soluble) and rains down to the deeper parts of the Ocean as detritus. Large Brown and Green algae, sea grasses and other plants of the ocean acquire Nitrogen from the Ammonia or Urea dissolved in the water, while organisms in the lower zones of the Ocean can filter feed Nitrogen from the detritus (these organisms are a part of the Nitrogen cycle, but are not plants obviously). Otherwise, algae typically grow to have a significant part of their bodies reach the surface, where they can fix Nitrogen directly. Aquatic: Either from ammonia released by bacteria, from bacteria living in the anaerobic 'soil' beneath the water or by growing to the surface and directly fixing the Nitrogen there.
