Final answer:
Whittaker created five kingdoms: Animalia, Plantae, Protista, Fungi, and Monera.
Step-by-step explanation:
Whittaker created five kingdoms in his classification system. These kingdoms are:
- Animalia - includes multicellular organisms that are heterotrophic (obtain energy from consuming other organisms).
- Plantae - includes multicellular organisms that are autotrophic (obtain energy from photosynthesis).
- Protista - includes unicellular eukaryotic organisms.
- Fungi - includes non-photosynthetic multicellular organisms that obtain nutrients by decomposing organic matter.
- Monera - includes prokaryotic organisms (bacteria and archaea).
