The Prickly Pear Cactus
Prickly pear cactus are found in all of the deserts of the American Southwest. Most prickly pears have large spines, actually modified leaves, on their stems and vary in height from less than a foot to 6 or 7 feet.

 

The Saguaro
Saguaros often begin life in the shelter of a "nurse" tree or shrub which provides a shaded, moister habitat. The largest plants are estimated to be 200 years old and can reach heights of 15 to 50 feet.

 

The Desert Food Chain
A food chain constitutes a complex network of organisms, from plants to animals, through which energy, derived from the sun, flows in the form of organic matter and dissipates in the form of waste heat.

 

The Desert Food Chain: The Role of Energy
Energy is the power to cause change. Plants use energy from the sun to grow and to flower. Animals use energy from plants to grow, reproduce and move. View the video to learn more!
