Life Cycles of Animals — Answer Key
Part A: Trace the Words
Trace each word carefully by following the dotted lines.
1. grow
2. adult
3. larva
4. cycle
5. pupa
6. egg
Part B: Fill in the Blank
Write the missing word or number on each line.
1. A hen lays an egg that hatches.
A pupa spins a silky 'cocoon' around itself for protection while it changes into an adult.
2. A caterpillar is also called a larva.
A tadpole slowly grows legs, loses its tail, and turns into a 'frog' that can hop on land.
3. A frog goes through a life cycle.
Chick eggs need to stay 'warm' so the baby inside can grow, and the hen uses her body for warmth.
4. A butterfly is the adult stage.
Caterpillars munch on green 'leaves' all day so they can store energy for the big change ahead.
Part C: True or False?
Read each statement. Circle True or False.
1. A chick grows into a hen or rooster.
True False
False — tadpoles hatch with just a tail and no legs; legs grow in later as they become frogs.
2. A pupa can fly around and eat.
True False
True — after resting as a pupa inside a cocoon or chrysalis, an adult butterfly breaks out with wings.
3. Frogs and butterflies both start as eggs.
True False
True — the baby inside an egg can only grow if warmth from the parent or the sun keeps the egg heated.
