Introducing invasive species to an ecosystem
What are invasive species and how do they impact ecosystem management?
Invasive species are non-native organisms that have no impact on the ecosystem they invade. They coexist peacefully with native species.
Invasive species are non-native organisms that cause harm to the ecosystem they invade. They can outcompete native species, disrupt food chains, and alter habitats.
Invasive species are non-native organisms that only cause harm to humans. They have no impact on the ecosystem.
Invasive species are native organisms that benefit the ecosystem they invade. They help improve biodiversity and restore balance.
Discuss the challenges associated with habitat fragmentation and its effects on biodiversity.
Increase in genetic diversity, larger population size, closer proximity of species, and enhancement of ecological processes.
Decrease in genetic diversity, smaller population size, decreased isolation of species, and improvement of ecological processes.
Loss of genetic diversity, reduced population size, increased isolation of species, and disruption of ecological processes.
No impact on genetic diversity, stable population size, no change in species isolation, and no effect on ecological processes.
