Freshwater fish

LARGE MOUTH BASS

the scientific name for the large mouth bass is Micropterus salmoides. They are reproducing rapidly and are becoming over populated. The bass is usually found in lakes and ponds. Mostly in murky water. They are omnivores and the things that hunt them are bigger fish and humans. Some interesting facts would be; there is competitions for finding the biggest bass, bass will eat EVERYTHING including trash, and there's not only a large mouth bass but also a small mouth bass.

Nitrogen cycle

First, the fish eat the food which turns into waste which is ammonia. Then the ammonia turns into nitrate and bacteria. Nitrite is turned into plant fertilizer and then the plants absorb the nitrate. Plants filter the water and clean it and then the water quality is improved and the fish are healthy.

Algae

When dissecting the algae to see what was in it I found lots of snails, scuds, and leaches. None of my fish ate them and they are still in my tank.

River model

The model goes p1 ripple p2 ripple p3 ripple p4. Mrs. Wood put in 6 orange meno, 20 brown meno, and 1 cray fish. After a couple days there was 2 brown in p2. 1 orange, 1 brown, and 1 cray in p4. And then she later on put 20 ghost shrimp in p3. There was pump deaths with the brown meno. 

Temperature and Density

In the demonstration the blue water was cold and the red water was warm. The blue/cold water is more dense than the red/warm water. And when the water is mixed the blue water goes to the bottom for the first jar and mixes and turn purple and then in the second jar the blue water stays on the bottom and the red on top. The red water slowly started cooling off in the second jar and started turning purple.

Water properties and issues

Lewisville lake is known to be crowded with people. It struggles with pollution and trash every day. Party cove is a huge example of things that would harm lewisville lake. People throw cans, food, tobacco and other harmful things in the water which eventually gets to the fish. There is usually 50-80 boats in one area and all of the gasoline from the boats is just seeping into the water. There is a lot of hazardous things fed into that lake every day.

Water cycle

Bridget and I chose the water cycle to show how important it is in our ecosystem. There is condensation, evaporation, precipitation, transportation, and accumulation. With out all of these we wouldn't have plants, lakes, or even drinking water. The water cycle has no beginning nor end. It is the source of everything we need today.
