Answer

  1. Bacteria and fungi

Explanation:

Antibiotics are chemical substances produced by microorganisms that can kill or inhibit the growth of other bacteria and fungi, thus used to treat bacterial and fungal infections. 

Many antibiotics like penicillin target bacterial cell wall synthesis, while others inhibit protein synthesis by targeting prokaryotic ribosomes. The ribosome serves the cell as a protein-making machine.

Viruses don't have cell walls or their own cellular machinery that can be attacked by antibiotics.
