WHAT IS AN ECOSYSTEM?

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

DESERT ECOSYSTEM.

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

CHARACTERISTICS OF THE DESERTS: 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.

DESERT FOOD CHAIN.

DESERT CAN BE SEPARATED IN:

Cold Hot and Dry Semiarid Coastal

COLD DESERT:

These deserts are characterized by cold winters with snowfall and high overall rainfall throughout the winter and occasionally over the summer.

HOT AND DRY DESERT:

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

SEMIARID DESERT: The summers are

moderately long and dry, and like hot deserts, the winters normally bring low concentrations of rainfall.

COASTAL DESERT: These deserts occur

in moderately cool to warm areas such as the Nearctic and Neotropical realm
