Why would finches need to develop
different shapes for their beaks?
Why would finches need to develop
different shapes for their beaks?
 Their beaks are adapted to the type of food
they eat (bugs, seeds, etc)

How is a cactus adapted to survive in a
hot, dry desert climate?
How is a cactus adapted to survive in a
hot, dry desert climate?
 Cactus are able to store water to last through
droughts. They have shallow roots. They
also have spines (leaves) to keep animals
form chewing on them.

colored because of pollution. Which
moth is more likely to survive?
You have light and dark colored
moths. The trees are becoming dark
colored because of pollution. Which

Describe the saying “survival of the
fittest”
Describe the saying “survival of the
fittest”
 Animals with stronger traits have a easier
time getting food, mates, and shelter. In turn
they get to live longer and reproduce more.
The “strong” traits get passed down while
“weak” traits eventually fade away.
