where do you cast your line? | where you think fish are feeding |
what do fish use cover for? | to escape and to help them ambush prey and To hidead from animals and protect fish |

What are the abiotic parts of an ecosystem? | Sunlight, air, water, minerals, temperature, and soil |
what are aquatic ecosystems? | Ecosystems organized around bodies of water |

What are some examples of invertebrates that are sensitive to pollution? | Stoneflies, caddisflies, and mayflies |
If you find these invertebrates what does that tell you about the water quality? | It's a healthy stream |
What do you know about a stream if these particular invertebrates are missing? | It's polluted |
What are two examples of pollution-tolerant invertebrates? | Blackfly larva and bloodworm |
what is Biodiversity? | a high number of species, as well as a high number of sensitive species living in a stream are good signs of a healthy stream |
describe the stream order... | headwaters/1st and 2nd order- have no rooted or floating plants, smaller fish live here 3rd-5th order- rooted and floating plants are here, support many types of animals |

A pond’s _______________ is fairly even throughout and changes with air temperature | temperature |
what are oxygen levels at in the air? | constant, staying around 21 percent all the time |
In a pond the oxygen levels can vary widely over the course of a day. Why? | Because water takes up oxygen from the air more slowly than animals in the pond |
What is happening in the day vs night with the oxygen levels? | Day: plants are photosynthesizing and giving off oxygen (raising oxygen levels in the water) Night: plants stop photosynthesizing. Animals use oxygen let over from the day |
what, other than plants, make oxygen for the body of water? | plant-like plankton |
Where is most of the plant life in a lake or pond? | In a ring a round the shoreline |
what is pond succession? | rosion brings sediment to the pond, replacing water with soil and creating more shallow areas. Decaying animals and plants fall to the pond bottom, adding to and enriching the sediment. This natural process is called pond succession |
_______________ that fills the pond also can bring pollution causing excess soil and plant nutrients to overload the pond and unbalance its growth cycle. | Surface water |
what does algae do for the pond? | algae overgrowth makes the water cloudy and shades out rooted plants. The dead algae uses up a lot of oxygen and causes the fish to die from a lack of oxygen. |
what can help keep ponds healthy? | Good Watershed management is important to keeping a pond healthy. Stopping excess erosion and runoff loaded with fertilizers, pesticides, or other pollutants is key. |
