Question

Male frogs and toads amplify their songs by ________.

1) Using their vocal sacs
2) Using their hind legs
3) Using their front legs
4) Using their tails

Answer 1

Male frogs and toads use their vocal sacs as resonating chambers to amplify their mating calls, which is essential for attracting females.

Step-by-step explanation:

Male frogs and toads amplify their songs by using their vocal sacs. These vocal sacs act as resonating chambers that enhance the sound of their calls, allowing them to be heard over greater distances. These calls are crucial for attracting females during mating season and can vary between different species of frogs. While frogs have powerful hind legs that are adapted for jumping, they do not use them to amplify their songs. As such, the correct answer to the question is that male frogs and toads amplify their songs by using their vocal sacs.
