1. How do constructed wetlands treat wastewater?
2. What is the difference between a damselfly and a dragonfly?
3. How does lake mixing work?
Two years ago I knew stuff about rocks, minerals, experiments, and ecosystems, yay!
Last year I knew stuff about amphibians, reptiles, freshwater, and more experiments, yay again!
Now I know stuff about oceanography, saltwater, and birds, yay for the third time!

1. I'm gonna guess. The sewage is run through the flora area and since it uses gravel the large molecules are caught and are used as nutrients for the plants. Not sure how the microscopic particles of turd are removed, maybe a filter at the end.
2. Damselflies have wings resting in a vertical position whereas dragonflies have horizontal wings.
3. Topwater gets cold, becomes denser, sinks down. The water at the bottom rises up. Idk much about the topic, nor do I know why all the diagrams show lake mixing in a cyclic motion. If you know, please tell me. The one thing in this event I'm actually half-decent in is the IDs.
If life gives you melons, you're dyslexic.

Why can't dinosaurs ski? Because they're dead.

1. Yep. There's also microorganisms (or macroorganisms idk) that feed on the organic material.
2. Correct.
3. I'm going to be real with you, I just thought of this question without knowing the answer so I'm going to assume you're correct because that's a logical answer.
Your turn!

Brain too fried from competition today, so here are some easy ones
[img]https://static.inaturalist.org/photos/11629088/large.jpg?1509811962[/img]
1. What organism is displayed in this picture?
2. Less than 0.1% of Earth's water is freshwater that is readily available for consumption. True or False?
3. What is an effect of nitrates on oxygen levels?

1. What is the basic principle which allows electric salinometers to function
2. What happens during Primary treatment of waste water?
3. Why do fish often contain high levels of mercury?

1. Idk. Conductivity?
2. Particles are removed from the wastewater via filtration and sedimentation.
3. Biomagnification occurs. Biomagnification is the property that higher trophic level animals will have a higher concentration of a toxin than those of lower trophic levels. In this case, fish would be around level 3-4, dependign on the type, so it would contain a higher concentration of toxins than the organisms of lower levels.

1. Hemimetabola describes what characteristic in macroinvertebrates?
2. What three orders have nymphs also known as naiads?
3. Name at least three forms of chlorine that are used in the disinfection stage in wastewater treatment.
