mammal life cycle Have less changes in their life cycle than insects or amphibians Develop inside mom’s body Babies drink mom’s milk
Draw, color and label a picture of each of the following life cycles:

Frog life cycle
Mammal life cycle
Life Cycle Stages of Animals Birth born or hatch Growth get bigger Development change into adults Reproduction produce young Death lives come to an end

Before a frog can live on land, how must its body change?
A frog must grow lungs so that it can breathe air and powerful legs to propel itself forward.
How is a mammal’s life cycle different from a frog’s or butterfly’s life cycle?
A mammal develops inside its mother, is born looking like its parents, and does not change a lot in its life cycle.
A frog or butterfly develops in an egg that the mother lays, hatches, and changes a lot in its life cycle.
Think about how mammals care for their young. Describe why this kind of care might be helpful for most mammals.
Young mammals are fed and protected until they learn how to live on their own and grow large enough to protect themselves.
