Which of the following is an example of an evasive species?

An evasive species refers to an organism that has established itself in a new environment and typically exhibits a rapid increase in population, often causing harm to the ecosystem it invades. Carp, specifically common carp, are often regarded as an evasive species in many regions, particularly in North America and Australia. They were introduced to various water bodies and have since outcompeted native fish species for resources, altered habitats through their feeding behaviors, and contributed to the degradation of water quality.

In contrast, tadpoles, salmon, and trout are generally not classified as evasive species in the same contexts. Tadpoles are often part of the normal life cycles of amphibians and play a role in their respective ecosystems. Salmon and trout, while they can be subject to environmental pressures and competition, are native to many regions where they exist, and their populations have evolved to coexist within those environments. Thus, the designation of carp as an evasive species highlights their significant ecological impact and the challenges they pose to local biodiversity.
