Final answer:
Biotic invasion by alien species depends on the characteristics of invading species and those of the invaded community. The success of invasion is influenced by the physiological and morphological traits of the invading species, as well as the state of the invaded community.
Step-by-step explanation:
Biotic invasion by alien species depends on both the characteristics of invading species and those of the invaded community. The success of invasion is influenced by the physiological and morphological traits of the invading species. Species with traits that allow them to adapt and thrive in new environments have a higher chance of successful invasion. Additionally, the characteristics of the invaded community play a role, such as native assemblages being depleted or disrupted, making the community more susceptible to invasion. Invasibility of aquatic systems is related to interactions among environmental variability, predictability, and severity.
