Multiple choice

Which of the following is NOT a benefit of seagrass meadows?

  1. Providing food and shelter for marine life

  2. Filtering pollutants and improving water quality

  3. Contributing to carbon sequestration and climate regulation

  4. Causing erosion and damaging coral reefs
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Seagrass meadows do not cause erosion or damage coral reefs; instead, they help stabilize sediments and provide a buffer zone between waves and the shoreline.

Multiple choice

Which water quality parameter is commonly used to assess the level of organic pollution?

  1. Dissolved oxygen

  2. Biochemical oxygen demand

  3. Chemical oxygen demand

  4. Total suspended solids
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Biochemical oxygen demand (BOD) is commonly used to assess the level of organic pollution in water, as it measures the amount of oxygen required by microorganisms to decompose organic matter.

Multiple choice

Which water quality parameter is commonly used to assess the level of nutrient pollution?

  1. Nitrate

  2. Phosphate

  3. Ammonia

  4. Total dissolved solids
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Nitrate is commonly used to assess the level of nutrient pollution in water, as it is a major form of nitrogen that can contribute to eutrophication.

Multiple choice

Which water quality parameter is commonly used to assess the level of sediment pollution?

  1. Total suspended solids

  2. Turbidity

  3. Secchi depth

  4. Light attenuation coefficient
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Total suspended solids (TSS) is commonly used to assess the level of sediment pollution in water, as it measures the amount of suspended particles in the water.

Multiple choice

  1. Fecal coliforms

  2. E. coli

  3. Enterococci

  4. Total coliforms
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

E. coli is commonly used to assess the level of microbial pollution in water, as it is a specific indicator of fecal contamination.

Multiple choice

Which water quality parameter is commonly used to assess the level of organic chemical pollution?

  1. Total organic carbon

  2. Dissolved organic carbon

  3. Biochemical oxygen demand

  4. Chemical oxygen demand
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Total organic carbon (TOC) is commonly used to assess the level of organic chemical pollution in water, as it measures the total amount of organic carbon present in the water.
