A company doing many river restoration projects across America to help trout.
What is trout unlimited?
This is the measure of the volume of water that is flowing in a stream or river at any given time
What is stream discharge?
Underground water contained in the empty spaces between soil particles and rock fissures
What is groundwater?
Light energy is converted into chemical energy in organic carbon compounds (such as glucose) through a chain of chemical reactions.
What is photosynthesis?
The richness of species living in an ecosystem
What is biodiversity?
When building roads across small streams engineers use these to redirect water.
What is a culvert?
Liquid water condensing from water vapor and falling from the atmosphere to the Earth’s surface.
What is precipitation?
The movement of water molecules to and from different storages and the transition between gaseous, liquid and solid states powered by the sun
What is the hydrologic cycle?
This is what organisms (such as plants) who synthesize their own organic compounds are called.
What is producers? (Or autotrophs)
An organism used to assess a specific environmental condition diversity of species living in an ecosystem
What is an indicator species?
What is a dam?
Liquid water at the surface becoming water vapor in the atmosphere
What is evaporation?
Water that remains on the Earth’s surface and runs downhill such as streams and rivers
What is runoff?
This is what organisms that get their organic compounds through feeding are called.
What is consumers? (Heterotrophs)
A technique of assessing and quantifying the health of an ecosystem
What is a biotic index?
A method of helping trout or salmon go around a dam using a human made, stairstep-like, waterfall.
What is a fish ladder?
The deepest point of a cross-section and will often have the greatest water velocity
What is a thalweg?
Water that soaks into the soil and ends up as groundwater
What is inflitration?
The name for all the different steps in a food chain or web.
Large (can be see with the naked eye) organisms without a backbone like insects, worms and shellfish that are found in a stream
What is a macroinvertebrate?
This is the name for when humans straighten the course of a stream and reinforce its banks to support buildings and property
What is channelization?
Water vapor escaping from plants
What is transpiration?
The hydrologic cycle can be broken up into these two categories.
What are storages and flows?
A summary of all possible chains within a system.
What is a food web?
A chart with a series of yes/no questions that allows you to narrow down the identification of a species
What is a dichotomous key?
