1. What is the difference between phytoplankton and zooplankton, and do they reside in lentic or lotic ecosystems?
2. How does a Secchi disk work?
3. Identify these two aquatic macroorganisms:[img]https://bit.ly/2PI7Xf5[/img]
1. Phytoplankton are autotrophs, meaning they produce their own energy while zooplankton are heterotrophs that consume other organisms for energy. They reside in lentic ecosystems.
2. The disk is lowered until it is not visible and that distance is measured to the nearest tenth of a meter.
3. I'm gonna guess... I have no clue. Mosquito and blood midge because why not.

1. Great answer.
2. I was looking more for how does it measure turbidity, but I guess I should have been more clear when asking. Your answer is good.
3. Crane fly and water mite larvae.
Your turn!

1. The blood midge contains large quantities of what protein that gives them their red color?
2. Disinfection of wastewater typically is done by what two substances?
3. What anatomical feature of mosquito larvae allows them to obtain oxygen above surface level while the organisms are still submerged?

1. Hemoglobin
2. Chlorine or chloramine
3. Siphon?

For 2, I was looking for chlorine and bleach. Everything else is good. Your turn.

1. Biochemical oxygen demand(BOD) refers to how fast organisms use up dissolved oxygen(DO). So, if the BOD of an aquatic ecosystem is higher than another, the DO will be lower because the organisms use up DO at a faster rate.
2. Mesotrophic lakes have an intermediate amount of nutrients whereas oligotrophic lakes are (more or less) depleted of nutrients.
3. Heavy metals

1. My turn, what is the quality of water?
2. How does carbonating water affect how much is sold?
3. Can you live without water if you breathed twice as much oxygen and hydrogen in a liquid form?

I doubt I need to hide these answers.
1. Generally referring to how potable it is
2. Indirectly proportionate as plain sparkling water is arguably complete garbage
3. It's hard to breathe a liquid but I've snorted water before so I'll say yes.
1. What organism is depicted in the image below?

2. A mayfly dun refers to what stage of its life cycle?
3. Name three illnesses associated with fecal coliform.
