The Water Cycle
When water falls from the clouds to the ground
What is precipitation?
The place where 78% of nitrogen found on earth is located
What is the atmosphere?
A small flowing body of water that moves across the land
What is a stream?
The flat parts on the fish's body to help them swim, balance, and turn in the water
What are fins?
A small round ball that a mother fish lays in the water
What is an egg?
When water gets warm from the sun and turns into gas that goes up into the air
What is evaporation?
Can change nitrogen into something useful (nitric acid)
What is lightning?
The layer of tree branches and leaves above the stream to give shade and keep water cool
What is a canopy?
Allow the trout to breathe underwater
When fish lay eggs so new baby fish can grow
What is spawning?
When water flows over the ground
What is surface runoff?
This group eats plants that have nitrogen
How do animals consume nitrogen?
Fallen branches, sticks, and/or logs in the stream
What is woody debris?
The small pouch of food that are attached to baby trout after it hatches
What is a yolk sac?
Baby trout that hatched from its egg; has a yolk sac and hides in the rocks
What is an alevin?
When water gathers in one place
What is accumulation?
This group gets useful nitrogen by the bacteria in the soil
How do plants consume nitrogen?
The land right next to the stream with plants, trees, and grass
What is a riparian zone?
The line along the side of the trout's body to help feel movement and vibrations for food and predators
What is the lateral line?
Young fish that finished using their yolk sac and swims around
What is a fry?
When plants release water from their leaves into the air
What is transpiration?
Some bacteria turn nitrogen into these forms for plants (Hint: You also saw it in the trout tank!)
What are nitrates and nitrites?
The shallow, fast-moving part of the stream where water flows over rocks (lots of oxygen)
What is a riffle?
The dark stripes on the sides of young trout to help blend in with rocks and plants from predators
What are parr marks?
The nest that female trout makes in the rocks at the bottom of the stream
What is a redd?
