Is eutrophication the process by which nutrients in a lake build up over time causing increase in algae?
Yes, eutrophication is the process where excessive nutrients, such as phosphorus and nitrogen, accumulate in a body of water, leading to increased algae growth and potentially harmful algal blooms. This can result in decreased oxygen levels and negative impacts on aquatic life.
How the excess use of fertilizer can affect the nitrogen and phosphorus?
Excess use of fertilizer can lead to nitrogen and phosphorus runoff into water bodies, causing eutrophication. This can result in algal blooms, depleting oxygen levels in the water and harming aquatic life. Additionally, the excess nutrients can leach into groundwater, contaminating drinking water sources.
What are 3 things that need to be removed from water?
Three things that need to be removed from water are pollutants (such as chemicals and heavy metals), pathogens (disease-causing microorganisms), and excess nutrients (like nitrogen and phosphorus) that can cause harmful algal blooms.
Why are nitrogen and phosphorus considered such key nutrients?
There are 17-18 nutrients that all are necessary for healthy soils and plants. For example, soils need the elements carbon, hydrogen, and oxygen. Needed soil elements are called macro and secondary nutrients, if their presence is required in greater amounts; and micronutrients, if lesser. The nutrients that are needed in greater amounts include nitrogen; phosphorus; and potassium, which is critical to the quality of the fruit. Lesser amounts are needed of sulfur, magnesium, and calcium. And still lesser amounts are needed of such nevertheless necessary elements as boron, cobalt, chlorine, copper, iron, manganese, molybdenum, nickel, and zinc. Nitrogen is critical to plant processes, such as photosynthesis. It's also critical to adequate coloring and growth of shoots. And it therefore is also critical to increased yield. Phosphorus is critical to overall plant health. For it promotes healthy root growth. It therefore is critical to the successful intake of water and nutrients, from the soil.
Which type of chemical lead to lack of dissolved oxygen?
Nutrient pollution, specifically excess nutrients like nitrogen and phosphorus, can lead to an overgrowth of algae. When the algae die and decompose, bacteria use up the dissolved oxygen in the water, causing hypoxia or oxygen depletion.
How does runoff of fertilizers affect eutrophication?
Runoff of fertilizers can lead to eutrophication by introducing excessive nutrients like nitrogen and phosphorus into bodies of water. These nutrients stimulate algal growth, causing algal blooms. When the algae die and decompose, it depletes oxygen levels in the water, leading to hypoxia or dead zones that harm aquatic life.
What is a area in which addition of an abundance of limiting nutrients like nitrogen and phosphorus causes an algal bloom blocking sunlight and causing the death of organisms below?
Red tide is an example. When severe enough they become harmful algal blooms which do damage to life beneath them in the water column.
''disadvantages of phosphorus''?
Excessive phosphorus levels in water bodies can lead to eutrophication, causing algal blooms and oxygen depletion. Additionally, phosphorus can contribute to water pollution and impact aquatic ecosystems by disrupting the natural balance of nutrients. In agriculture, over-application of phosphorus fertilizers can lead to soil degradation and runoff, affecting water quality.
What would happen if you added fertiliser to waterweed?
Adding fertilizer to waterweed can promote its growth by providing essential nutrients like nitrogen and phosphorus. However, excessive fertilizer can lead to nutrient runoff, causing algae blooms and disrupting the balance of the aquatic ecosystem. It's important to use fertilizers sparingly to avoid negative impacts on the environment.
Why is there a large increase in ionic radius from silicon to phosphorus?
The increase in ionic radius from silicon to phosphorus is due to the addition of an extra electron in the outermost shell of the atom. This added electron increases the electron-electron repulsion forces, causing the electron cloud to expand and the ionic radius to increase.
What are nutrients that build up in a lake over time causing an increase in algal growth?
I'm pretty sure it's eutrophication
Why does eutrophication lead to depletion of oxygen in water?
Eutrophication occurs when excessive nutrients (such as phosphorus and nitrogen) enter a body of water, causing overgrowth of algae and other aquatic plants. As these plants die and decompose, bacteria consume oxygen during the decomposition process, leading to oxygen depletion in the water. This depletion can harm aquatic organisms and disrupt the balance of the ecosystem.
