What are invasive species?

• A. They are native organisms that maintain ecosystem balance
• B. They are mammals exclusively living in forests
• C. They are non-native organisms that disrupt ecosystems
• D. They are beneficial insects that support tree growth

Answer: (C)

Invasive species are defined as non-native organisms that introduce disruptions into the ecosystems where they are found. When these species establish themselves in a new environment, they can outcompete local flora and fauna for resources such as food, light, and space, ultimately leading to detrimental impacts on biodiversity and ecosystem function. This disruption can result in the decline or extinction of native species, changes in nutrient cycling, and alterations in habitat structure. Understanding the nature of invasive species is crucial for effective ecosystem management and conservation efforts, as controlling or eradicating invasive species can help restore balance to affected ecosystems. The other options do not accurately represent the characteristics of invasive species; they either refer to native organisms, specific classifications of mammals, or beneficial insects, none of which encapsulate the concept of invasiveness and its ecological consequences.
