Questions

1. A caterpillar is the larva stage of which insect?

   1. Dragonfly
   2. Butterfly or moth
   3. Grasshopper
   4. Ant
   Show answer

   Answer: Butterfly or moth

   Caterpillars are the larva stage of butterflies and moths. They eat leaves and grow before forming a chrysalis.

2. Frogs lay their eggs on dry land.

   Show answer

   Answer: False

   Frogs lay eggs in water or in moist places. The eggs need water to develop into tadpoles.

3. What stage comes after the egg in complete metamorphosis?

   1. Pupa
   2. Adult
   3. Nymph
   4. Larva
   Show answer

   Answer: Larva

   In complete metamorphosis the order is egg → larva → pupa → adult. Larva comes right after the egg.

4. A young grasshopper that looks like a small adult is called a ___.

   Show answer

   Answer: nymph

   Nymphs look like miniature adults. Grasshoppers, crickets, and dragonflies use this simpler three-stage cycle.

5. A chrysalis is another name for the pupa stage of a butterfly.

   Show answer

   Answer: True

   When a butterfly caterpillar enters the pupa stage, it forms a hard protective case called a chrysalis. Moths form a cocoon made of silk instead.

6. Which animal does NOT go through metamorphosis?

   1. Beetle
   2. Moth
   3. Eagle
   4. Housefly
   Show answer

   Answer: Eagle

   Eagles hatch from eggs as chicks and grow into adults without any metamorphosis. Beetles, moths, and flies all go through complete metamorphosis.

7. A tadpole breathes underwater using gills.

   Show answer

   Answer: True

   Tadpoles have gills that extract oxygen from water. As they develop legs and mature into frogs, they develop lungs for breathing air.

8. How many stages does incomplete metamorphosis have?

   1. Two
   2. Three
   3. Four
   4. Five
   Show answer

   Answer: Three

   Incomplete metamorphosis has three stages: egg, nymph, and adult. Complete metamorphosis has four stages.

9. The final stage in any animal life cycle is the ___ stage.

   Show answer

   Answer: adult

   Adult is the final and reproductive stage. Adults can mate and produce eggs to begin the life cycle again.

10. All insects go through exactly the same life cycle stages.

    Show answer

    Answer: False

    Insects use either complete metamorphosis (4 stages) or incomplete metamorphosis (3 stages). They do not all share the same cycle.
