Name the following:
The organisms that can be called natural purifiers of the air.

Hint: A system that eliminates pollutants from the air in a room to improve indoor air quality is known as an air purifier or air cleaner. These machines are often advertised as being helpful to allergy and asthma sufferers, as well as limiting or removing secondhand cigarette smoke. In the medical, manufacturing, and commercial sectors, commercial air purifiers are available as small stand-alone devices or bigger units that can be coupled to an air handler unit (AHU) or an HVAC unit.

Complete answer:
Plants and Green Algae may also be considered natural air purifiers. Both make use of carbon dioxide and turn it into the oxygen we need to survive on this planet.
This activity is made possible by the presence of chlorophyll in each of them. Plants are multicellular species that are mostly photosynthetic eukaryotes in the Plantae kingdom.
Plants were traditionally classified as one of two kingdoms, one of which included all non-animal living creatures, and the other of which included algae and fungi.
Fungi and some algae, as well as prokaryotes, are currently excluded from all existing descriptions of Plantae (the archaea and bacteria).

Note:
Photosynthesis by primary chloroplasts resulting from endosymbiosis with cyanobacteria provides the majority of the energy for green plants. Chlorophylls a and b, which give them their green color, are found in their chloroplasts. Some plants are parasitic or mycotrophic, meaning they lack the ability to produce chlorophyll or photosynthesize but can produce flowers, fruits, and seeds. Sexual reproduction and generational alternation are common in plants; though asexual reproduction is also common.
