    The property of containing salt

    The amount of suspended solids

    Describes the condition of the water

  • Question 3
    30 seconds
    Q.

    What is dissolved oxygen?

    answer choices

    The property of containing salt

    The amount of suspended solids

    Where are nitrates and phosphates found?

    answer choices

    Fertilizer

  • Question 5
    30 seconds
    Q.

    Why are too many nutrients (like nitrates and phosphates) bad for our waters?

    answer choices

    Nutrients decrease the pH of the water, causing it to become increasingly acidic

    Nutrients change the salinity of the water

    Wetlands filter out runoff that may contain nutrients

    Nutrients in the water cause too much algae growth, which decrease the level of oxygen in the water
