Ecosystems
Ecology: A branch of biology that deals with the relationships of organisms to one another and to their environments. - Ed.-
An ecosystem is a biotic community together with its physical environment, considered as an integrated unit. Implied
within this definition is the concept of a structural and functional whole unified through life processes. An ecosystem
may be characterized as a viable unit of community and interactive habitat. Ecosystems are hierarchical and can be
viewed as nested sets of open systems in which physical, chemical, and biological processes form interactive
subsystems. Some ecosystems are microscopic and the largest comprises the biosphere. Ecosystem restoration can be
directed at different-sized ecosystems within the nested set, and many encompass multiple states, more localized
watersheds, or a smaller complex of aquatic habitat.
Put another way, each organism (including humans) is affected by and interacts with its environment. That
environment is formed from a combination of interactive non-living and living elements. The non-living elements
include: energy, water, air, substrate, and chemical constituents such as nutrients. The living elements include
plants, vertebrate animals, invertebrates, and microorganisms. When we consider both forms of elements and their
interactions as a single entity, we have an ecosystem at some level of organization.¹

Ecosubsections
An area or region of land designated for study purposes that has distinct characteristics setting it apart from others. In the Mojave, two general ecosections, separated by geomorphic boundaries, are further classified into ecosubsections.Desert Ecosystems

Deserts host plants and animals living in what strikes many humans as oppressive environments. Solar energy that green plants convert into food
fuels life here. Although in most ecosystems plants compete for sunlight, here most plants are adapted to minimize the effects of too much solar
energy.

Habitats
Habitats are environments that are inhabited by a specific plant species or animal.Flora & Fauna
Specific plant and animal species, and communities within, and around desert ecosystems.Vegetation*
Within the environment lie the ecologies of biomes composed of habitats forming thier own environment. This is scaleable to all levels of environmental habitats. - Ed.Desert Habitat Summaries

Biome
A major biotic community characterized by the dominant plant life and the climate that generally prevails.
Ecology
The study of the natural interaction of organisms to one another within their environment.
Food Chains
A food chain, in ecology, is a hierarchical series of transfers of energy in an ecological community according to the order of predation using the next usually lower member as a food source. - Ed.
