Within these well-written pages, Alcock exposes us to the plant and animal life of a land many regard as desolate. Parasitism is where one organism lives in close proximity to another organism, but one organism benefits from the interaction and the other is negatively impacted. Plants provide both nutrients and most of the water needs of the species. A Red-Tailed Hawk building a nest in a Saguaro Cactus is an example of commensalism in the desert. Have them share the pairs they came up with and the relationship between the two organisms. and Brown-headed Cowbird (Molothrus ater) parasitism were the most common causes of nest failure, we conclude that the impacts of climate change-caused drought on annual reproductive output in the Sonoran Desert will be further compounded by parasitism and predation for Black-tailed Gnatcatchers and by predation for Verdins. Similar to the Mojave desert tortoise, the Sonoran desert tortoise feeds almost exclusively on plants, with plants making up 95% of its diet.

One common species is the palo verde ("green stick" in . While the mistletoe is growing, the mistletoe acquires nutrients from the willow tree. An example of mutualism in the hot and dry desert is the relationship between a Gobi woodpecker and a cactus. They will drink water when it is available, but are not dependent on it since the moisture-rich flesh of their prey satisfies their water needs. The theory that the balance of ecosystems can rely on one keystone species was first established in 1969 by American zoology professor Robert T. Paine. The Sonoran Desert National Monument is a half-million acre BLM property to the south of Pheonix in Arizona. Categorize and apply the three types of symbiotic relationships of organisms (mutualism, commensalism, parasitism).
