The document describes ecosystems and characteristics of desert environments. It discusses how desert plants and animals have adapted to the hot, dry conditions by being drought and salt tolerant. Solar energy fuels life in deserts. Common desert plants include cacti, yucca, and bushes. Animals found in deserts include lizards, tortoises, frogs, camels, rats, coyotes and toads. The document classifies deserts into cold, hot and dry, semiarid, and coastal types based on temperature and rainfall patterns.

2.  Ecosystems are dynamic
interactions between
plants, animals, and
microorganisms and their
environment working together
as a functional unit.

3.  Desert plants and animals
living in what strikes many
humans as oppressive
environments. Solar energy
that green plants convert into
food fuels life here.

4.  Soils that form in arid
climates are predominaly
mineral soils with low
organic content.
 Most plants are drought-
salt tolerant.
 Rain does fall occasionally
in deserts, and desert
storms are often violent.
 Also they are very hot
during the day and very
cold during the night.

11.  Thesedeserts are
characterized by cold
winters with snowfall
and high overall rainfall
throughout the winter
and occasionally over
the summer.

12.  The seasons are
generally warm
throughout the year
and very hot in the
summer. The winters
usually bring little
rainfall.

13.  The summers are
moderately long and
dry, and like hot
deserts, the winters
normally bring low
concentrations of
rainfall.

14.  Thesedeserts occur in
moderately cool to
warm areas such as the
Nearctic and
Neotropical realm
