Which of the following describes the interactions between introduced and native species?

The correct answer highlights the complexity of interactions that can occur when introduced species enter a new ecosystem and interact with native species. These interactions can encompass a range of relationships, including competition for resources, predation where one species preys on another, and the spread of diseases that can affect native populations.

For example, when an introduced species competes for food or habitat with a native species, this may drive the native species towards decreased populations or even extinction. Similarly, an introduced predator may not have natural predators in the new environment, leading to explosive population growth and significant impacts on native prey species. Additionally, introduced species can bring new diseases to which native species have no immunity, causing further declines in those populations.

The other options misrepresent the interactions entirely; claiming that only competition exists overlooks the multifaceted nature of ecological interactions. Suggesting no interactions occur ignores the reality that ecosystems are interconnected. Likewise, stating that introduced species only benefit native species contradicts evidence showing that introduced species often have detrimental effects. Thus, recognizing the spectrum of relationships encapsulated in the correct answer is crucial for understanding ecological dynamics.
