Cavalier-Smith's model no longer separates prokaryotes and eukaryotes is the statement which differs from kingdom classification.

Explanation:

Cavalier-Smith in 1998 had reduced the kingdom numbers. The were brought down from 8 to 6. These are:

Animalia

Protozoa

fungi

plantae

chromista

bacteria

He divided eukaryotes into 6 kingdoms.  The kingdoms are refined for better classification.

While Carolus Linnaeus divided the organisms into two kingdoms

Animalia and plantae.

The five kingdom classification:

Monera (prpkaryotes)

Protista  ( unicellular eukaryotes)

fungi (multicellular decomposers)

plantae (multicellular producers)

Animalia (multicellular consumers)

It has drawbacks like in kingdom monera both autotrophs and heterotrophs  are included. Phylogeny is not explained in lower organisms of monera and protista. Virus is also in classification. Cavalier-Smith introduced a new kingdom called chromista which are single- celled or multicellular eukaryotic organisms as diatoms, algae, oomycetes and protozoans which perform photosynthesis.
