The northern Pacific sea star is a particularly successful in invasive species. Which of the following explains why it is so successful, in the waters of southeastern, Australia, outside of its native environment.

Answer 1

The northern Pacific sea star is successful as an invasive species in southeastern Australia because:

1. Lack of natural predators: In its native environment, the northern Pacific sea star has natural predators that help keep its population in check. However, in southeastern Australia, these predators may be absent, allowing the sea star to reproduce and thrive unchecked.

2. Fast reproduction rate: The northern Pacific sea star has a high reproductive rate, allowing it to quickly colonize new areas and outcompete native species for resources. This rapid reproduction can help the sea star establish a strong presence in its new environment.

3. Generalist feeding habits: The northern Pacific sea star is a generalist feeder, meaning it can consume a wide variety of prey species. This adaptability allows the sea star to easily find food sources in its new environment and outcompete native species that may have more specialized diets.

4. Ability to tolerate a range of environmental conditions: The northern Pacific sea star is able to tolerate a wide range of environmental conditions, including temperature, salinity, and water quality. This flexibility allows the sea star to thrive in different habitats and outcompete native species that may be more sensitive to changes in their surroundings.
