Explanation:

Members of the phylum Sporozoa have simple body organization due to their parasitic mode of life; all of them being endoparasitic and pathogenic. Locomotory and food-capturing sub-structures are absent due to parasitic life. They are always heterotrophic and saprozoic in nutrition. Sporozoa generally show alternation of generation between asexual and sexual generation, and are monogenetic or digenetic. Life cycle always involves the formation of haploid cells called sporozoites.
