Water quality

The water cycle has three main stages. Evaporation, (a)   , and Precipitation

Water should have a PH that is considered ( Acidic, Basic, or Neutral )

(a)  

A water test that looks at how clear or cloudy the water is:

• PH Test

• Turbidity Test

• Oxygen test

• Nitrate/Nitrite test

• Macro-invertebrates test

High turbidity means the water is:

• Clear

• Cloudy

• has NO particles blocking light

• has particles blocking light

High tubidity creates poor water because: Check all that apply

• Particles block sunlight making it hard for plants to photosynthesize in the water.

• Particles can be bacteria or other pathogens that are bad for organisms living in the water

• creates water that has a strong current making it hard for animals to swim.

Plants being present to produce oxygen is really important because that oxygen allows animals to thrive in the water ecosystem. To test how much plants are producing, you would use a probe to perform a (a)   oxygen test.

A water ecosystem with little to NO dissolved oxygen is considered a (a)   because life simply cannot thrive there without oxygen

Nitrates and Nitrites are important nutrients for plants to grow. Too much of these leads to algae growth on top of the water. When this occurs, they block sunlight for plants under the water which eventually leads to loss of plants, loss of oxygen, and death of animals. This process is called:

• Eutrophication

• Biomagnification

• Bioaccumulation

• Food Web Stabilization

____________ is when toxins build up as you move up the trophic levels. Generally organisms on the lower trophic levels live but apex organisms end up being affected as levels rise within the food chain.

• Biomagnification

• Bioaccumulation

• Food Web Stabilization

____________ is when a single organism builds up a toxin as it lives/feeds throughout its life. Older individuals are found with much more of that toxin than younger ones
