An individual person does not have to reproduce in order to survive, but the species only continues to exist if reproduction takes place.

The function of a reproductive structure is to procreate. The structures exists in order cor the creation of more organisms.
Plants and animals need reproductive systems in order to reproduce. A species that does not reproduce will eventually become extinct.

No animals impregnate themselves. Even hermaphrodites such as earthworms, which possess both male and female reproductive systems - have to exchange sperm with another of their species in order to reproduce.
The biological hierarchy from kingdom to species is Kingdom, Phylum, Class, Order, Family, Genus, Species.
