Community
A species with defined male and female sexes is referred to as dioecious. In contrast, hermaphroditic species have both male and female reproductive organs, enabling them to change sex as needed.
A group of the same species in a defined area is called a population. Populations are characterized by their size, density, distribution, and demographics. They are a key focus in ecology and conservation biology, as understanding population dynamics helps in the management and preservation of species.
