Who am I?
By: Antonio and Akira
I am in North America. It is hot
and dry. My winter brings a
little rain. What biome am I?
• Desert
• Grassland
Great!
• In the day it goes up to 100˚F and at night it
goes down to 40-60˚F.
• The maximum temperature ranges from
43.5˚C - 49˚C.
• The minimum temperature sometimes drops
to -18˚C.
• No humidity
• Two inches of rain per year
Wrong!!!
• I have a lot of sand.
My leaves are waxy to…
• Keep water inside.
• Catch flies.
Correct!!
• I can grow new plants from my own
roots.
• The leaves on me reflect the sun so it
keeps me cool.
