A graph compares native and invasive species populations before and after introduction.
After invasion, the native population declines. The most likely mechanism is:
- Acheck_circle
Competition for resources, predation, or disease introduced by the invasive species
- B
Genetic drift in the native species
- C
Speciation in the invasive species
- D
Climate change unrelated to the invasive
Explanation
Invasive species often outcompete or prey upon natives and may introduce novel pathogens, leading to native declines.
