What are four different adaptations that desert plants have? im not very aware of desert plants can some people tell me this answer.

 To survive, desert plants have adapted to the extremes of heat and aridity by using both physical and behavioral mechanisms, much like desert animals. 

Plants that have adapted by altering their physical structure are called xerophytes. Xerophytes, such as cacti, usually have special means of storing and conserving water. They often have few or no leaves, which reduces transpiration. 

Phreatophytes are plants that have adapted to arid environments by growing extremely long roots, allowing them to acquire moisture at or near the water table. 

Other desert plants, using behavioral adaptations, have developed a lifestyle in conformance with the seasons of greatest moisture and/or coolest temperatures. These type of plants are usually (and inaccurately) referred to as perennials, plants that live for several years, and annuals, plants that live for only a season. 

Desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available.

The answer your looking for is a food chain grid. it describes how nature can support itself and survival of the fittest comes into play..
