Ecology: Death Valley National Park

Death Valley Ecosystems

& Natural Features

An ecosystem is how it all works together. The geology of region provide for the plants, which provide for the animals that eat the plants and animals that eat these animals, all of which have adapted to the environment in which they live. Ecosystems may not be defined by hard boundaries, a line in the sand so to speak. They could end abruptly according to dramatic changes in terrain or composition of the soil, but, more often than not they may have a transition from one to the other. These transitions are called ecotones. Ecotones may include plant and animal species indicative of one or both ecosystems. These ecotones may sometimes be considered ecosystems in themselves.
