What are the 3 main domains of life?
The three-domain system is a biological classification introduced by Carl Woese et al. in 1990 that divides cellular life forms into archaea, bacteria, and eukaryote domains. The key difference from earlier classifications is the splitting of archaea from bacteria.
What two groups are animals divided into?
The animal kingdom is divided into two groups: vertebrates and invertebrates. Vertebrates have been around for millions of years but have evolved and changed over time. The word vertebrate means “having a backbone.” Many animals have backbones. You have a backbone.

What is the order of classification of species?
There are seven main taxonomic ranks: kingdom, phylum or division, class, order, family, genus, species. In addition, domain (proposed by Carl Woese) is now widely used as a fundamental rank, although it is not mentioned in any of the nomenclature codes, and is a synonym for dominion (lat.

Which classification system is best and why?
Bacteria cannot be called plants because they are prokaryotic organisms and some of them even possess flagella which helps in movement. This is why the five kingdom classification is the best and is adjusted according to the drawbacks in the two kingdom classification.
