Explanations: answer key for all 10 questions

Q1: What is the usual order of a frog's life cycle?
Answer: Egg, tadpole, froglet, adult
This change is called metamorphosis.
Q2: What are clumps of frog eggs called?
Answer: Frogspawn
Jelly protects the eggs.
Q3: How do young tadpoles breathe?
Answer: With gills
Lungs develop later.
Q4: What happens to a tadpole's tail?
Answer: It is absorbed into the body
Its nutrients are reused.
Q5: Which hormone triggers metamorphosis?
Answer: Thyroid hormone
Iodine is needed to make it.
Q6: How does a tadpole's diet usually change?
Answer: From plants to insects
Its gut shortens as it changes.
Q7: What do newt larvae have on the sides of their heads?
Answer: Feathery external gills
Most absorb them as adults.
Q8: What is unusual about the axolotl's life cycle?
Answer: It stays in larval form as an adult
This is called neoteny.
Q9: How long can bullfrog tadpoles take to develop?
Answer: Up to two or three years
Cold water slows growth.
Q10: Why do most amphibians need water to breed?
Answer: Their eggs lack shells and dry out
Some lay eggs on wet leaves instead.

Amphibian Life Cycles Trivia – From Egg to Adult

Most amphibians have a life cycle with two very different stages. They hatch from soft, shell-less eggs laid in water as aquatic larvae, then change into land-dwelling adults through a process called metamorphosis.

In frogs, tadpoles breathe with gills, eat plants and swim with tails. Over weeks or months, they grow legs, develop lungs and absorb their tails, turning into froglets. Thyroid hormone controls this transformation, which also changes their gut and diet.

Not all amphibians follow the same path. Some frogs skip the tadpole stage, axolotls keep their larval features for life and some salamanders give birth to live young. Clean ponds and wetlands are essential for amphibians to complete their life cycles.
