Some current research efforts are investigating whether or not , a group of prokaryotes with the ability to produce oxygen as a by-product of photosynthesis, can be used as a source of renewable energy by converting sunlight into electricity.

Explanation:

Simple cyanobacteria (single-celled organisms that can produce oxygen through photosynthesis) played a key role in providing Earth’s atmosphere and oceans with oxygen

Cyanobacteria or the blue green algae are the only bacteria that contain chlorophyll A, a chemical required for oxygenic photosynthesis, the process which uses carbon dioxide, water and sunlight to produce oxygen and glucose (sugars) for energy

In this process chlorophyll A helps in capturing the energy from sunlight

In addition to chlorophyll A, blue-green algae also contain the pigments phycoerythrin and phycocyanin, which give the bacteria their bluish tint    

All the above characteristics of cyanobacteria can be used as a source of renewable energy by converting sunlight into electricity

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.

straight probes are used primarily for measuring flow as it is approaching the test area. its geometry allows the probe to be mounted so that it is in the direct line of airflow.
