Explanation:weathering is a term by which rocks get broken down on the earths surface into things like sediments or clays and soil.
I think the correct answer would be the third option. Organisms that help break down dead organic material so it can be recycled into a usable form for other organisms are called decomposers and this would include some of the bacteria. Also, there is a number of bacteria that are capable of breaking down some of the harmful products like in recent studies there are bacteria that could dechlorinate the toxic PCB substance. Some bacteria, as well, lives in the human intestines which aids in the breaking down of the food into useful molecules. The third option is partially true since there are some bacteria like the cyanobacteria which produces oxygen but it does not contribute largely to the oxygen present in the atmosphere.
The correct answer is - C. genus and species.
The final scientific name of an animal represents two things, its genus, and its species.
The first name is the genus of the animal, in this case we have Canus. The second name is the species of the animal, in this case nipponicus.
All living organisms are classified in a same manner: kingdom, phylum, class, order, family, genus, species.
Since the name Canus reminds me a lot of Canis, I will take the wolf as an example:
Kingdom: Animalia
Phylum: Chordata
Class: Mammalia
Order: Carnivora
Family: Canidae
Genus: Canis
Species: C. Lupus
