Considering the characteristics and impacts of invasive species, which of the
following statements best describes the common ecological consequences of
invasive species like lionfish, cuckoos, and fire ants on native ecosystems?
Invasive species such as lionfish, cuckoos, and fire ants primarily benefit native
ecosystems by providing new food sources for native predators and filling vacant
ecological niches.
Invasive lionfish in Atlantic coral reefs primarily cause ecological disruption by
overgrazing on marine vegetation, leading to habitat degradation.
Invasive cuckoos in European ecosystems reduce the populations of native bird
species by laying their eggs in the nests of host birds, which leads to decreased
reproductive success of the host species.
Invasive fire ants in North American environments enhance native species
diversity by preying on other invasive species, thereby restoring ecological
balance.
