Use these definitions of important terms as you answer the Everglades Focus Questions.

aquifer A geologic formation that contains sufficient saturated permeable material to yield economically significant quantities of water to wells and springs.
ecosystem The interacting system that encompasses a living community and its non-living physical environment.
evapotranspiration The conversion of water from a liquid to a vapor including the evaporation of water vapor from plants.
hydrologic cycle The water cycle, which includes evaporation, precipitation, and flow of water to the seas. The hydrologic cycle supplies terrestrial organisms with a continual supply of freshwater.
levee A natural or artificial bank that constrains the flow of water to a channel.
peat A spongy organic substance made of decayed plant fibers.
water budget The freshwater available for plant, animal, and human use plus the water necessary to maintain streamflow.
watershed All of the land that drains into a particular body of water.
wetland Land that is transitional between aquatic and terrestrial ecosystems and is covered with water for at least part of the year.

These tables allow you to compare crops by the amount of water used to raise them. For example, which crop requires more irrigation - miscellaneous vegetables or sweet corn? Which crops require a lot of water? Which ones need very little? Which crops did farmers plant more of in 1990 than in 1985? Are these crops ones that use a lot of water?
