Explanation:
Taxonomy actually means “arrangement law”. It is the branch of biology that deals with the classification of organisms.
The taxonomic classification system was invented by Carl Linnaeus. It is a hierarchical model of classifying living organisms based on shared characteristics.
Dogs are referred to as 'man's best friend' partly owing to some level of taxonomic relationship between the two species. Dogs and man belong to a class of vertebrates known as mammals- one of the shared characteristics of mammals is that they give birth to their young ones alive.
The taxonomic classification of man is:
Domain: Eukaryote - Kingdom - Animalia Phylum - Chordata Subphylum - Vertebrata Class - Mammalia Order - Primates Family - Hominidae Genus - Homo Species - sapiens.
The taxonomic classification of dog is:
Domain: Eukaryote - Kingdom - Animalia Phylum - Chordata Subphylum - Vertebrata Class - Mammalia Order - Carnivora Family - Canidae Genus - Canis Species - lupus familiaris

Explanation:
Option D is incorrect, as increased photosynthesis would increase oxygen supply present, not carbon dioxide supply.
Option C is incorrect, as increased decomposition would increase carbon dioxide released and oxygen present is reduced, not increased.
Option A is unlikely as if this were the case, increased oxygen levels would enable bluegill fish to survive as well.
