Final answer:
The cane toad, native to South and Central America and introduced to Australia, is an invasive species that has disrupted local ecosystems by poisoning native predators.
Step-by-step explanation:
One well-documented invasive species is the cane toad (Bufo [Rhinella] marina), which is native to South and Central America. Introduced to Australia in 1935 to control insect pests, the cane toad has since had a significant negative impact on the environment. Due to their poisonous glands, cane toads pose a threat to native predators that attempt to eat them, resulting in a decline in the populations of these predatory species. This example illustrates how invasive species can disrupt local ecosystems and food webs, often leading to severe ecological and economic consequences.
Additionally, Asian carp can disrupt ecosystems by altering food chains and damaging aquatic vegetation.
