* Monera (Bacteria and Archaea): These single-celled organisms perform cellular respiration to obtain energy from organic molecules.
* Protista (Algae, Protozoa, etc.): These eukaryotic organisms also carry out cellular respiration, often alongside photosynthesis.
* Fungi (Mushrooms, Yeasts, etc.): Fungi obtain energy through respiration, breaking down organic matter for nutrients.
* Plantae (Plants): While plants are well known for photosynthesis, they also perform cellular respiration to utilize the energy stored from sunlight.
* Animalia (Animals): Animals rely entirely on cellular respiration to break down food and fuel their bodily functions.
Therefore, all five kingdoms undergo cellular respiration in some form. It is a crucial process for all living organisms to extract energy from nutrients and sustain life.
