Cane Toads in Australia

In Australia, cane toads are...

• Used as food for humans

• Helpful to the environment

• Harmful to the environment

• Used as food for farm animals

Why were cane toads brought to Australia, and why did it turn out to be a major failure?

• To control agricultural pests; inability to reach beetles

• To enhance biodiversity; rapid reproduction

• To serve as pets; resistance to poison

• To improve soil quality; adaptation to various environments

How do cane toads reproduce, and why are their offspring dangerous?

• Rapidly lay eggs; offspring are poisonous

• Slow reproduction; offspring are harmless

• Asexual reproduction; offspring have no poison

• Hibernate during reproduction; offspring are venomous

Why do cane toads have no natural predators in Australia?

• Predators are not interested in toads

• Predators developed immunity to the poison

• Predators are scared of toads

• Predators cannot find toads in the wild

According to evolutionary biologist Rick Shine, what impact have cane toads had on Australia's biodiversity?

• Increased biodiversity

• No impact on biodiversity

• Decline in predator species

• Improved ecosystem balance

What is one strategy mentioned in the passage for controlling the spread of cane toads?

• Feeding predators sausages with cane toad poison

• Encouraging cane toads to reproduce

• Building more canals for toads to thrive

• Introducing more foreign species to combat toads

How did researcher Daniel Florane address the issue of cane toads accessing moist environments?

• Built fences around canals

• Introduced more water sources

• Encouraged cane toads to move freely

• Provided canals with additional protection

What role do meat ants play in the battle against cane toads?

• They help cane toads reproduce

• They are immune to cane toad poison and attack them

• They serve as food for cane toads

• They contribute to the decline of native species

How does the approach with meat ants address past mistakes made in dealing with invasive species?

• It introduces a new invasive species

• It repeats the same mistakes

• It relies on foreign predators

• It involves native species immune to cane toad poison
