How does eutrophication lead to the death of fish in aquatic ecosystems?
Eutrophication, caused by excessive nutrients like nitrogen and phosphorus entering water bodies, leads to algal blooms. These blooms reduce oxygen levels in the water when they decompose, suffocating fish and other aquatic organisms.
Why can't fish live out of water?
Fish cannot live out of water because they rely on water to breathe. Fish have gills that extract oxygen from water, and without water, they are unable to get the oxygen they need to survive. Additionally, their bodies are adapted to the buoyancy and support provided by water, so being out of water puts stress on their organs and can lead to suffocation and death.
What are the main threats to coral reefs posed by coral-eating fish, and how can their impact be mitigated?
Coral-eating fish can threaten coral reefs by overgrazing on the coral, which can lead to coral death and reduced reef health. Their impact can be mitigated by managing fishing practices, protecting key herbivorous fish species, and promoting coral reef conservation efforts.
Is death a disease?
No, death is not a disease. Death is a natural and inevitable biological process that occurs as a part of life. While diseases can lead to death, death itself is the cessation of all biological functions.
Do the disease keloid cause death?
Keloids are not typically life-threatening and do not directly cause death. However, they can lead to complications such as infections or emotional distress.
What effect can fertilizers an sewage have on rivers?
Fertilizers and sewage can significantly harm rivers by introducing excess nutrients, particularly nitrogen and phosphorus, which lead to eutrophication. This process causes algal blooms that deplete oxygen levels in the water, harming aquatic life and disrupting ecosystems. Additionally, pollutants from sewage can introduce pathogens and toxins, further degrading water quality and posing risks to human health and wildlife. Overall, these contaminants can lead to a decline in biodiversity and the overall health of river ecosystems.
How does toilet water end up in a river?
Toilet water can end up in a river through the municipal sewage system. Wastewater from toilets is transported through pipes to treatment plants where it is treated before being discharged into rivers or other bodies of water. Improperly functioning sewage systems or illegal dumping can also lead to toilet water entering rivers.
How does sewage flow into rivers in Kenya?
This happens a lot in slum areas. In these slum areas, they have no indoor plumbing. So, they have to deficate and urinate anywhere they can outside. Many people make "flying toilets" this is where people deficate in a bag, tie it up, and fling it. Besides raw sewage, garbage is also thrown into these rivers where people wash and drink, and children often play there too. Playing in sewage and garbage can lead to many life threatening diseases for these children, such as cholera.
Does the toilet souage lead to the sea?
Yes, in many areas, sewage systems can eventually lead to the sea. Wastewater treatment facilities process toilet sewage before discharging treated effluent into rivers, lakes, or directly into the ocean. However, the specifics can vary greatly depending on local infrastructure and regulations. In some regions, untreated sewage can also be released into the sea, particularly during heavy rainfall or system failures, leading to environmental concerns.
What can rivers lead up to?
Rivers can but aren't limited to lead up to... oceans, lakes, ponds, or other rivers.
Is coffee toxic to Betta fish?
Yes. Most anything placed in the water, other than chemicals intended for fish use, can overly stress a fish that can lead to death if not outright kill the fish.
What are the potential health risks associated with a sewage gas leak?
Potential health risks associated with a sewage gas leak include respiratory issues, headaches, nausea, dizziness, and in severe cases, exposure to toxic gases like hydrogen sulfide can lead to unconsciousness or even death.
Does human sewage discharge pollution affect plant growth?
Sewage is a rich source of nitrogen and phosphorus which facilitates plant growth. As "night soil" sewage is a historic fertilizer in much of the third world. In urban areas sewage is often contaminated with heavy metals (lead, chrome, zinc) and may impact plant growth. In water sewage encourages algal growth leading to eutrophication and algal blooms which in turn deplete oxygen levels causing fish kills.
What is small rivers that lead into bigger rivers?
Tributaries.
What makes rivers lead all the state's rivers in producing electricity?
Hawaii has no rivers.
Why does stream water collect in rivers?
because all streams lead to rivers and rivers lead to the sea and water is collective and gathers in the most siutable area.
How does storm water affects the loacl beaches?
Sewage in beaches is capable of killing fish. Sewage usually contains higher than normal lead content. Lead is poisonous to fish and plankton. Sewage should only be diverted to a treatment plant.
