The document discusses the life cycles of different animals. It defines key terms like embryo, larva, pupa, and nymph. It explains that insects have either a 3-stage life cycle of egg, nymph, adult or a 4-stage cycle of egg, larva, pupa, adult. Other animals progress from egg to embryo to young animal to adult. The document contrasts the life cycles of cockroaches and butterflies. It also compares fish, frogs and mammals in terms of their characteristics like having backbones, lungs or gills, laying eggs, and caring for young.

5. embryo

6. What is the stage in the insect life
cycle between the larva and the adult?

7. pupa

8. What is a young insect that has a

9. larva

10. What is an animal with a backbone
that lives part of its life cycle in water

11. amphibian

21. 3 stage Insects: egg, nymph, adult
4 stage Insects: egg, larva, pupa, adult
Other animals: egg, embryo, young
animal, and adult
At egg stage, the embryo grows until it is born or hatched; the
young animal feeds and continues to develop;
the adult can reproduce

22. How is the life cycle of a cockroach
different from the life cycle of a
butterfly?

23. A cockroach has a 3 stage life cycle
And a butterfly has a 4 stage life cycle.
A young cockroach, or nymph, has the
same body form as an adult cockroach.
A young butterfly is a caterpillar, and it
has a different shape than an adult
butterfly.

24. How are fishes, frogs, and mammals
alike and how are they different?

25. Alike: Fishes, frogs, and mammals all have
backbones and need oxygen to live.
Different: Mammals and adult frogs have
lungs, while fishes and tadpoles get oxygen
by using gills. Fishes and frogs lay eggs,
but most mammals do not lay eggs. Unlike
fishes and frogs mammals have hair or fur, and
mammal mothers produce milk to feed their babies.

26. What are some things that some
adult animals do for their young?

27. Some animals, such as birds and
