Can you tell me the difference between a bacterium, a virus, a fungus and a parasite?

Bacterium: A bacterium is an organism that can reproduce asexually by dividing itself. It has a cell wall made of peptidoglycan and a cell membrane composed of phospholipids.2 Virus: A virus is a small infectious agent that replicates only inside living cells. It has a genome consisting of either DNA or RNA surrounded by a protein coat.3 Fungus: A fungus is a large eukaryotic organism that reproduces sexually by releasing spores into the environment. It has a cell wall made of chitin and a cell membrane composed of ergosterol.4 Parasite: A parasite is an organism that lives off another organism. It has specialized adaptations such as a mouth, gut and reproductive system to feed on its host.
