What else can I help you with?
You are walking in a clear-cut section of forest a few days after a heavy rainstorm. a near by stream is very muddy and has many dead fish what might have happened?
The heavy rainstorm likely caused increased runoff from the surrounding landscape, washing sediment, pollutants, and organic matter into the stream. This influx can lead to decreased oxygen levels in the water, ultimately harming aquatic life, which explains the presence of dead fish. Additionally, the muddy conditions suggest erosion, which may have contributed to the stream's poor water quality.
What are the characteristic of a fast moving stream ecosystem?
Fast-moving stream ecosystems tend to have high oxygen levels, cool temperatures, and a diverse array of aquatic species adapted to the swift currents. These streams often have rocky bottoms with well-oxygenated water that supports a variety of fish, invertebrates, and plant life. The fast flow of water helps maintain water quality by preventing the accumulation of pollutants and sediment.
What happens to organisms in a stream when nitrates leak from a factory?
Excess nitrates in a stream can lead to eutrophication, causing algal blooms that block sunlight and deplete oxygen when they decay. This can harm aquatic organisms, such as fish, by reducing oxygen levels and disrupting the food chain. High nitrate levels can also be toxic to some species of organisms in the stream.
What effect does the pollution have on the gulf stream?
Pollution, particularly from land runoff and atmospheric deposition, can impact the Gulf Stream by altering the salinity and temperature of ocean waters. Increased nutrient levels from agricultural runoff can lead to algal blooms, which deplete oxygen and disrupt marine ecosystems. Additionally, the introduction of pollutants can affect the Gulf Stream's currents and strength, potentially leading to changes in climate patterns. Overall, these effects can compromise the vital role of the Gulf Stream in regulating global climate and weather systems.
Rainbow trout can they live in ponds?
Noo. Rainbow trout can not live in pond water. That depends on the temp., oxygen level, and some type of fresh water. like a water change, or a small stream. a fountain, waterfall, and the stream will help with oxygen levels.
How does oxygen enter the stream?
Oxygen enters the blood stream through the air sacs in you lungs.
What is the most likely result of nitrate pollution of a stream?
Nitrate pollution of a stream can result in eutrophication, where excess nutrients lead to excessive plant and algae growth. This can deplete oxygen levels in the water, causing harm to aquatic organisms and disrupting the ecosystem balance. Additionally, nitrate pollution can contaminate drinking water sources and pose health risks to humans.
What is the connection between organisms in a stream and the dissolved oxygen level?
Organisms in streams need oxygen to live when lacking dissolved oxygen it will kill these organisms. edit: unless the organisms in the stream are photosynthetic, in which case they will increase the oxygen levels. however, by far, most organisms in a stream are not photosynthetic and oxygenation occurs solely through aeration and surface area dissolving from the air. so, to answer the question, organisms (most organisms which aren't plant-based photosynthetic organisms) decrease the amount of oxygen in a stream. edit: a flowing stream has turbulence which helps aerate the water, increasing dissolved oxygen. In contrast, stagnant water tends to be low in dissolved oxygen, except near the surface. Multicellular animals (like fish) need a good supply of dissolved oxygen to thrive.
Where is oxygen content in a river or stream likely to be the highest?
The oxygen content of a river or stream is likely to be highest at the source. The source of the river or stream is where it originates.
where does oxygen enter the stream?
In air breathing animals, oxygen enters the blood stream through the alveoli, tiny sacs in the lungs. In water breathing animals oxygen enters the blood stream through the gills.
What happens to the soil when it is washed into a stream?
When soil is washed into a stream, it can cause water pollution by clouding the water, reducing water clarity, and affecting aquatic life that depend on clean water. The excess sediment in the stream can also impact the health of the stream ecosystem by reducing oxygen levels and altering habitats for aquatic species.
Which has more dissolved oxygen a stream or a lake?
there is more dissolved oxygen present in a stream because the movement and the bubbling of the air allows more oxygen to be ingested
