Quizziz for Water Quality & Water Pollution Test

The presence of a substance in the environment that produces undesirable health or environmental effects is the definition of...

• oxygen
• pollution
• turbidity
• hypoxia

Which of the following IS NOT an example of a pathogen?

• viruses
• bacteria
• organic waste
• parasitic organisms

Turbidity is...

• A description of how clear a water sample is
• A description of how thick the water is
• How much oxygen is dissolved in a water sample
• How many pathogens are present in a water sample

Eutrophication occurs when...

• oil leaks into a water source
• the pH of a water source is too acid
• fertilizer run-off enters a water source
• when arsenic is added to water source

According to this illustration, how is the concentration of Mercury changing in the environment?

• Mercury levels are decreasing.
• Mercury levels remain constant.
• Mercury levels increase.
• Mercury levels increase and then decrease.

Which organism experiences the largest amount of biomagnification?

• algae
• insects eating fish
• insect eating insects
• fish eating fish

POP's stands for Persistent Organic Pollutants. These are chemicals that...

• block sunlight from marine environments
• do not easily break down in the environment
• remove dissolved oxygen from the environment
• increases the temperature of the environment

3 results of eutrophication are:

• decreased oxygen, decreased diversity, and stinky, stagnant water
• increased temperature, increased photosynthesis, and increased oxygen levels
• decreased oxygen levels, increased diversity, and improved water quality
• increased oxygen, improved water clarity, and decreased photosynthesis

According to this graph, what happens to the amount of oxygen dissolved in water as the temperature of water increases?

• Oxygen levels decrease as temperature increases.
• Oxygen levels do not change.
• Oxygen levels increase as temperature increases.
• Oxygen does not dissolve in water.

The pH of this test strip is...

• 1
• 3
• 6
• 9
