14 Questions
Why are invasive species like the mongoose so successful in non-native environments?
Native species in the new environment lack adaptations to defend against the invasive species.
What usually determines if a species is considered invasive in a particular area?
The extinction of native species it causes or threatens.
Why might an introduced species be considered invasive in one area but not in its native habitat?
Native species in the new environment have defense mechanisms against the introduced species.
What effect can co-evolution between a predator and its prey have on their relationship?
It creates a balance within the predator-prey relationship.
How does the absence of predators in a new habitat affect the population of an introduced species?
It results in unchecked reproduction of the introduced species.
What factor differentiates an invasive species from a non-invasive one?
Their threat level to native species.
Why are non-native species like the mongoose often considered invasive?
They lack predators in the new habitat, leading to unchecked reproduction.
What is a key reason why an introduced species can be invasive in a new area but not in its native habitat?
Native species in the new area are not equipped to deal with the introduced species.
What contributes to the success of invasive species like the mongoose in non-native environments?
Their reproductive advantage due to absence of predators.
What ecological impact does an invasive species like the mongoose have on a new habitat?
Causing a decline in native populations due to lack of adaptation.
How does the absence of predators affect the population dynamics of an introduced species in a new habitat?
It allows the introduced species to thrive and outcompete native species.
What distinguishes an invasive species from a non-invasive one in a particular area?
The impact of the introduced species on native populations.
Why do non-native species often thrive in new habitats?
Since they are not subject to predation in these habitats.
What is one reason why an invasive species may not cause ecological harm in its native habitat?
It has natural predators that limit its population growth
