Abiotic—The non-living component of an ecosystem.
Absorption—The process that occurs when water (and nutrients) in the soil is taken up by the root systems of plants and used for their physiological processes.
Aquifer—An underground formation of permeable rock, sand or gravel that holds vast amounts of water.
Biotic—The living component of a community.
Climax community—The final stage in the process of succession.
Condensation—The process that occurs when water vapor cools and turns into drops that will form precipitation.
Community—All of the living things in a given area.
Decomposers—Organisms, such as bacteria and fungi, that break down organic matter or detritus into nutrients which may be recycled through the ecosystem.
Dehydration—The movement of water out of a body or object.
Detritus—Partially decomposed plants and other organisms.
Ecological succession—The progressive change in the plants and animals, and non-living factors of an ecosystem over time.
Ecosystem—The community and the nonliving environment that function together as an interdependent unit.
Emergent plants—Plants that are rooted in the bottom and extend out of the water
Eutrophication—The "aging" of a water body due to the addition of organic matter.
Evaporation—The process that occurs when water enters the air in the form of a gas called vapor.
Free floating plants—Plants that have roots in the water which are not attached to the bottom.
Food chain—The flow of energy from one organism to the next within a community.
Food web—The interconnected pattern of separate food chains in a community.
Groundwater—Water below the water.
Habitat—The place where an organism lives.
Infiltration—The process that occurs when water soaks into the ground (as compared to runoff).
Limiting factor—Too much or too little of an abiotic factor which can prevent an organism from living in a specific environment.
Osmosis—The movement of a dissolved substance across a membrane (as of a living cell) from areas of high concentration to lower concentration.
Phytoplankton—Microscopic free floating plants found in the water column.
Precipitation—The process of water falling to the Earth as rain, mist, snow, sleet, or hail.
Producers—Green plants that utilize sunlight to make their own food through the process of photosynthesis
Primary consumers—Animals that feed only on producer organisms.
Secondary consumers—Animals that feed on primary consumers.
Submergent plants—Plants that are rooted in the bottom and do not extend above the water surface.
Surface runoff—Water which directly flows across the land into streams, rivers, or lakes.
Terrestrial—Anything related to the land or its inhabitants, as compared to water or air.
Transpiration—A process that occurs when water absorbed by plant roots is drawn through the body of a plant and then evaporates from the surface of leaves and stems.
Trophic level—Each successive level of producers and consumers in a food chain.
Water table—The upper limit of a portion of the soil that is totally saturated with water.

Careers in Florida's Freshwater Environments
This fast-paced musical DVD and companion booklet introduces middle school students to the many occupations needed to protect and preserve our lakes, rivers and wetlands. Included are introductions to jobs in wildlife, fisheries, plants, water chemistry, recreation, information, and teaching. Some occupations require a high school education, some require college, but emphasis is placed on the fact that all jobs require that students learn what they are studying in school right now.
