Define an invasive species.

An invasive species is a non-native species that is introduced to a new environment and has the potential to cause harm to the ecosystem, economy, or human health. These species can outcompete native species for resources, disrupt natural habitats, and spread rapidly, often with negative consequences for the environment.

An invasive species, also known as a non-native or alien species, is a species that has been introduced into an environment outside of its natural range. Invasive species can pose significant ecological and economic threats to native species and ecosystems.

Characteristics of invasive species include:

- High reproductive rates
- Wide environmental tolerance
- Ability to outcompete native species for resources
- Ability to alter the physical or chemical characteristics of the environment
- Negative impacts on native species and ecosystems
