Desert Ecosystems

Standard 3a Students know ecosystems can be characterized by their living and nonliving components.

Standard 3b Students know that in any particular environment, some kinds of plants and animals survive well, some survive less well, and some cannot survive at all.

3. What are some special features of desert life?

 

Desert plants are different from plants in other ecosystems because they have to live and grow with very little water.  Plants have shallow roots so that they can soak up any rain that falls in this dry environment.

Plants store water in their stems and have sharp needles that keep animals from eating them to get their water.

 

 

  Most desert animals are nocturnal, that means they hunt for food at night when it's cooler.

Many desert animals fur, feathers, or skin is light in color because the light color reflects the hot desert sun

Why does a desert tortoise spend most of its life underground?

  It's trying to stay cool
  It's trying to stay warm
 
It's hiding from other tortoises

4. Can you make a desert food chain?

Desert - very hot all year with very little rain.  Plants and animals are adapted to conserving water. What's it like where you live deserts
