Question
Hint:
1. Keystone species
2. Sea star Pisaster ochraeous
3. Invasive species
4. Stable
Keystone species would have a disproportionate impact on the community, thus making the community unstable if it were removed.
The most well known example of a keystone species is the intertidal sea star Pisaster ochraeous.
Invasive species are invaders who are not native to the habitat and create disruption to the ecosystem.
Stable community is one that can withstand, or at the very least rebound from these changes.
