Question

The cane toad, or Rhinella marina, was introduced to the Hawaiian Islands in 1932 by sugar cane farmers. The farmers released the toads in their crops to help control pests that were damaging the sugar cane. The cane toad has few natural predators because it secretes a poisonous toxin that kills the animals that consume it. As a result, the cane toad population thrived, and by 1935, it numbered hundreds of thousands. Which role does the cane toad play in the Hawaiian islands?

Answer 1

invasive species

Step-by-step explanation:

from edge

Answer 2

The answer is invasive species.

Invasive species are species that are not native to the specific ecosystem, but they are capable of spreading widely through the ecosystem. This way they can threaten native species of the ecosystem or cause environmental harm.
After being introduced into the Hawaiian Islands, the cane toads greatly affect local ecosystem. In the new area, they have a few natural predators and are able to spread. If they spread beyond the area they are introduced, they become invasive species which can overgrow native biotopes and are a great threat to the local biodiversity. This could lead to the extinction of some native species.
