Deserts

Adaptations of -Producers-Plants store water in their leaves and stems to hold in as much water as possible. Producers also have long, wide spanning root systems below the surface to collect as much water as possible.

Adaptations of-Consumers-Many mammals avoid the high daytime temperatures by being nocturnal. Organisms may burrow themselves in the ground to escape the heat.Owls often gape open-mouthed and flutter their throat to cool themselves by evaporating water from their mouth.

Secondary SuccessionDeserts lack rain fall, and when they receive rain it often causes flash flooding. In the Mojave National Preserve, the most likely cause of a disaster would be a drought or a flash flood. In either case, soil would already be present and a whole multitude of different grasses and wildflowers including Big Galleta, Indian Rice Grass, Bush Muhly, Fluff Grass, Red Brome, and Desert Needle would be able to inhabit the land.

-Keystone Species-Some species of hummingbirds are keystone species in the Sonoran Desert of North America. Hummingbirds pollinate many varieties of native cactus and other plants. In areas of the Sonoran Desert with few hummingbirds, invasive species such as buffelgrass have taken over the ecosystem.

-The Armadillo-Common Name :ArmadilloScientific Name: Dasypus novemcinctusArmadillos usually prefer to build burrows in moist soil.The Armadillos role in the environment is mostly eating termites and insects that inhabit plants.This makes the Armadillo a secondary consumer.The Armadillo is a K-Strategist. They usually only have one offspring a year, and can live up to 15 years. They also share a Type II survivorship curve. There is much competition for territorial space and a mate within the species. Armadillos are predators of many ants, beetles, slugs and eggs of birds.
