1. What is a desert like ?
Deserts are
very dry. They have hot days and cold nights.
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
