Homework worksheet for matching life cycle stages of butterfly, fish, frog, and human with their descriptions.

Let's solve each section of this homework step by step, matching the descriptions to the correct life cycle stages.

---

Butterfly Life Cycle

Stages:
- A. Adult
- B. Egg
- C. Larva
- D. Pupa

Descriptions:

1. Most of the feeding takes place, young stage.
→ This describes the larva (caterpillar), which eats a lot to grow.
✔ 1 – C. Larva

2. Inactive stage, growing, often well-camouflaged.
→ This is the pupa stage (chrysalis), where the butterfly undergoes metamorphosis and doesn't eat or move much.
✔ 2 – D. Pupa

3. The unborn stage.
→ This is the egg, the first stage in the life cycle.
✔ 3 – B. Egg

4. The final stage, breeding, usually grow wings.
→ The adult butterfly emerges from the pupa, has wings, and reproduces.
✔ 4 – A. Adult

Fish Life Cycle

Stages:
- E. Adult Fish
- F. Eggs
- G. Juvenile Fish
- H. Larvae

Descriptions:

5. Laid by the female into the water column, fertilized by a male.
→ This is the eggs stage.
✔ 5 – F. Eggs

6. Lay eggs or fertilize eggs and the fish life cycle begins again.
→ This refers to the adult fish, which reproduce.
✔ 6 – E. Adult Fish

7. Spend large amounts of time in the water, eaten by predators.
→ This describes larvae, the tiny, vulnerable early stage after hatching.
✔ 7 – H. Larvae

8. Survivors develop and continue to grow, often called fry.
→ "Fry" are young fish that have hatched and are developing — this is the juvenile fish stage.
✔ 8 – G. Juvenile Fish

Frog Life Cycle

Stages:
- J. Eggs
- K. Frog
- L. Froglet
- M. Tadpole

Descriptions:

9. Develops in the egg, breaks open, it swims out, has gills.
→ This is the tadpole stage — it hatches from the egg and lives in water with gills.
✔ 9 – M. Tadpole

10. Body changes, prepares for life outside of water, develops hind legs.
→ This describes the froglet stage, when tadpoles begin to transform and grow legs.
✔ 10 – L. Froglet

11. Male fertilizes them in jelly-like fluid.
→ Frogs lay eggs in jelly-like masses, and the male fertilizes them externally. So this is the eggs stage.
✔ 11 – J. Eggs

12. Loses tail, fully developed, lives out of the water, ready to breed.
→ This is the frog stage — fully matured adult frog.
✔ 12 – K. Frog

Human Life Cycle

Stages:
- N. Adolescent
- O. Adult
- P. Baby
- Q. Before Birth
- R. Child

Descriptions:

13. Becomes more mature, life cycle begins again.
→ This refers to the adult stage, when one can reproduce and start the cycle anew.
✔ 13 – O. Adult

14. Before age 13 and after infancy.
→ This is the child stage (typically ages 1–12).
✔ 14 – R. Child

15. Largest changes include puberty and sexual development.
→ This is the adolescent stage, marked by puberty.
✔ 15 – N. Adolescent

16. Egg produced and is fertilized in the female.
→ This happens before birth — the zygote forms and develops in the womb.
✔ 16 – Q. Before Birth

17. Must depend on a parent for care, have more bones than adults.
→ This describes a baby — newborns need care and have more bones (around 270) than adults (206).
✔ 17 – P. Baby
