Where do bacteria fix nitrogen gas?
Bacteria fix nitrogen by taking the nitrogen in the air and turning it into a type of nitrogen that can be used by other organisms. This usually occurs in the form of ammonium.
What is the limiting nutrient for algae growth phosphorus nitrogen or carbon?
All three are limiting nutrients for algae growth, along with light.
What plant family helps return nitrogen to the soil?
Legumes fix nitrogen in the soil.
List five ways in which algae are useful to us?
(i) kelps- obtained from brown algae, are sources of iodine and potassium.(ii)blue-green algae like ANABAENA and NOSTOC are able to fix nitrogen in the form of nitrates and thus increase the fertility of soil..(iii) an antibiotic CHLORELLIN is obtained from the algae Chlorella..(iv) red algae is used in the preparation of agar agar , which is used in jellies and ice-creams..(v)iodine is produced by the brown algae- Laminaria which occurs in sea....(vi)diatoms- obtained from green algae are used to make metal polish,porcelain, toothpaste, glass, etc........
What are methods of nitrogen fixation that complete the nitrogen cycle?
nitrogen fixation takes place with the help of lightning , bacteria called rhizobium lives in the nodules of legumenous plants convert nitrogen into nitrogeous compounds , algae etc. also helps in nitrogen fixation
Which organisms fix nitrogen in aquatic ecosystems?
normal name: blue-green algae scientific name: cyanobacteria
What effect would there be on the marine environment if there was a large decrease in the number of blue green algae in an area?
There would be a decrease in productivity because the algae "fix" nitrogen needed for protein production.
Algae help return nitrogen to the soil?

Most nitrogen is fixed by what?
The fixing of nitrogen is an important part of the nitrogen cycle. Nitrogen fixing bacteria fix the nitrogen back into the atmosphere.
What is major difficulty for algae?
acquiring nitrogen
How does algae benefit mankind?
Its a biological nitrogen fixer.
Does algae provide nitrogen?
Algae participates in a process called nitrogen fixation. In this process, Nitrogen (N2) is removed from the air and converted into ammonia (NH3). This process is especially important due to the need for ammonia in the biological process of biosynthesis.
Why do chemical fertilizers provide nutrients to algae?
Fertilizers contain high concentrations of nitrogen, a limiting nutrient for algae.
