According to the Enemy Release Hypothesis:
a.
Predators and pathogens experience population increase when invasive species become extinct
b.
Invasive species allow other species in the habitat to escape their normal enemies
c.
Predators and pathogens have significantly greater ability to invade other habitats than any other organisms
d.
Invasive species perform well in foreign habitats as they because not face their normal enemies
e.
Invasive species replace the native enemies of resident species
Which of the following best describes a keystone species?
a. An organism, whose introduction causes or is likely to cause environmental harm
b. An organism, who if removed, the entire ecosystem changes.
c. Can signal a change in the biological condition of a particular ecosystem and diagnose the health of that ecosystem
d. Can indirectly protect several other species in the same habitat
Give an example of how invasive species have taught about the importance of predators or herbivores. For your example, explain where it happened, what organisms were involved, and what was short-term ecological outcome. What was the long-term (current) outcome? What, if anything, changed the course of this outcome?
