What is the concept of major and minor phyla?
The concept of major and minor phyla is based on two factors: (i) The number of species and individuals; (ii) Their participation in ecological communities. … Whereas, the minor phyla form only a fraction of animal communities. On this basis, the two phyla, Rotifera and Ectoprocta, cannot be considered as major phyla.
