Bacteria -
Bacteria is very simplest nd prokaryotic organism. It was discovered by Antony von leeuwnhock Robert Koch nd Louis pasture. They are present in water, air nd land. There size is 2-10 meu. Reproduction is by fission. There cell wall is thick which is made of chitin.
Algae -
They are found in river, pond, sea, lack etc. They are unicellular or multicellular. They are autotrops due to presence of chlorophyll. Food store in form of starch.
Virus -
They are non cellular, obligate parasites. They have only one kind of nucleic acid either DNA or RNA. Virus are nit affected by levels of antibiotics that cells can tolerate.

hey user..!!
here is ur ans..
=============================
BACTERIA : 1. Unicellular, independent/ parasitic organisms. Sometimes many bacteria together form colonies.
2. Bacterial cell is prokaryotic with cell wall,but
distinct nucleus or cell organelles are absent.
=============================
VIRUSES :
2. They are found in the form of independent particles. Virus is a long molecule of DNA or RNA covered by a protein coat.
==============================
ALGAE : 1. They are aquatic.
2. Eukaryotic, unicellular, autotrophic organisms.
3. Photosynthesis is carried out with the help of chloroplast present in the cell.
==============================
PROTOZOA : 1. Protozoans are found in soil, fresh water and sea water. Some are found in the body of other organisms with eukaryotic cell.
==============================
