1. Large invertebrate (organism without a backbone) that can be seen with the unaided eye
2. Just under the surface of the water/stagnant water
3. A riffle is where fast-moving water flows over rocks (usually shallow). A pool is deep, slowmoving water.
4. Microhabitats: Under/on rocks, on leaf packs, on live plants, in riffles, on top of water, swimming
throughout water, in sediment
5. CPOM=course particulate organic matter=large/whole leaves, needles and twigs
6. Shredder—EX. Cranefly larva
7. Dragonfly, damselfly, water strider, crayfish, stonefly, beetles, dobsonfly/hellgrammite
8. From oxygen in the air (outside the water)
9. Snorkel—have a tube/appendage that extends out of the water from the body
Scuba—take a bubble of air under with them
10. From oxygen dissolved in the water
11. Gills, absorb through the skill directly, from piercing plants
12. Hydropneustic
Aeropneustic
13. I would say it is “good” water quality because even though the mayfly and stonefly are group I and
the cranefly and blackfly are from lower groups (II and III), the mayfly and stonefly must have good
quality.
