All of the options you provided can contribute to an invasive species outcompeting a native species, but here's a brief explanation of each:
1. **They have no predators so they can spread rapidly**: This is a significant factor. In their new environment, invasive species might not have natural predators, allowing their populations to grow unchecked. This lack of predation can give them a competitive advantage over native species.
2. **They are introduced by humans at high rates**: Human activities often facilitate the spread of invasive species, whether through global trade, transportation, or intentional introduction. The higher the rate of introduction, the more likely it is that an invasive species will establish and spread in a new area, potentially outcompeting native species.
3. **They use the same shelter or space**: Competition for habitat can be critical. If invasive species occupy the same niches or use the same physical space as native species, they can limit the resources available to the natives, leading to their decline.
4. **They eat the same food resources**: Invasive species that consume the same food sources as native species can outcompete them, especially if they are more efficient at foraging or have a broader diet. This can lead to a reduction in food availability for native species.
Overall, multiple factors often work together to allow invasive species to successfully outcompete native species in a given ecosystem.
