When Algae runs out of the proper nutrition it needs such as phosphates and other minerals it dies. Algae then dies and starts to decay during the decaying process Algae uses oxygen which is also why fish die from lack of oxygen. So to answer this question yes Algae does decay and consume oxygen.

What is a algal bloom that occurs in the ocean called?
when there is an excess of nitrogen (for example when all the snow melts in the spring and washes nutrients into bodies of water), blue green algae / Cyanobacteria can grow very rapidly and essentially coat the surface of the water. This creates problems for any underwater vegetation because the sunlight it needs to grow is being blocked out by all of the algae growing above it. This problem is reflected in all of the species of animals that eat the vegetation and etc down the food chain, because cyanobacteria is not good food for zooplankton and fish. Eventually the blue green algae will run out of nutrients and will die off and the bacteria that bloom to consume the dead blue green algae consumed oxygen and in extreme situations the oxygen supply in the body of water (in smaller closed off bodies such as ponds or lakes) can be depleted by all of the dead decomposing algae and this can kill fish and other species.
What are red tides caused by?
Red tides are a natural phenomenon caused by an increase in the amount of nutrients that algae need usually due to farm runoff. When the amount of nutrients reaches a certain level there is a significant increase in Karenia Brevis algae. Many also believe that red tides occur when there is a combination of very high temperatures, wind, and rainfall.Red tides is mostly caused by the increase of temperature and the difference of temperature between hot surface and a cold layer beneath the hot surface. When it is night, the dinoflagellates move to the cold layer to absorb nutrients. When it is day, they move to top to photosynthesize.Red tides are caused by algal blooms. Certain types of algae in the ocean multiply at rapid rates, typically by excess nutrients found in the water. The algae die and the decay process consumes the oxygen in the water -- one of the reasons these red tides are so destructive.By the way, not all algal blooms are red. It all depends on the algae present which grow quickly.A bloom of red algae, usually due to increased nutrients in the water.These extra nutrients can come either from natural sources or human caused pollution.The red algae both deplete oxygen in the water and produce toxins, which kill fish and other sealife. The toxins can also kill people if they eat seafood (especially filter feeders e.g. clams, mussels, oysters, scallops) caught during the period of the red tide or immediately afterwards.
Do soaps have thesame effects on eutrophication?
Soaps often contain compounds called phosphates. Phosphate has the chemical formula PO4, meaning one phosphorous atom and 4 oxygen atoms. Phosphates are always combined with another element, such as sodium or calcium. so typically you see ingredients like NaPO4, and so on, instead of just phosphate. In addition, in soaps, the ingredients are often named with "organic" descriptions, from organic chemistry, that are hard to decipher. However, you can usually see the word "phosphate" in there somewhere. All living organisms need phosphorous, and they can get it from dissolved phosphates. Typically plants and microbes absorb phosphate and it enters a food chain. It is vital. The problem is that when you put too much (put too much Tide in your washing machine, wash your dishes with a quart of dish soap, to exagerrate mildly) soap in an environment, the phosphates stimulate the producers at the bottom of the food chain to overproduce, because they have much more phosphorous than is naturally and normally available. Algae is one such "producer". Too much phosphate stimulates tons and tons of algae to grow in a water ecosystem that is polluted. The algae literally blocks to absorption of oxygen at the surface, because the atmosphere can't really make contact with the water- the dense algal "bloom" is in the way. In addition, the algae blocks sunlight to oxygen producing organisms lower down in the water. Also, as the algae dies, oxygen using micro organisms that eat dead algae also experience a huge boom in population, using up the oxygen that does exist. All of this seems slightly counter intuitive, because algae itself is an oxygen producer. You can see, however, why massive amounts of it cause de-oxygenation of water. In turn, of course, animals are killed- they enter oxygen free water and die of lack of oxygen, and you get giant fish kills. Other organisms that need oxygen die as well. If this happens very often, an ecosystem can be completely disrupted, everything gets out of balance, extinctions occur, and we have once again damaged things beyond fixing.
Doe weeds give us oxygen?
yes they do because they suck in carbon dioxide then turn it into oxygen if they didnt then sirtan types of fish would die out. yes they do because they suck in carbon dioxide then turn it into oxygen if they didnt then sirtan types of fish would die out.
What will happen if plants do not get carbon dioxide?
If plants don't get carbon dioxide, they won't be able to take water from the soil to get sugar from sunlight; this sugar is called "Glucose" which is food for a plant, and plants need sugar so they can break it down to get the energy that they need to avoid wilting. Carbon dioxide enters the plant through the leaves and comes back out of the plant as oxygen from the water in the soil, and the carbon dioxide turns into sugar
How does algae growth affect dissolved oxygen levels?
Algae growth can lead to fluctuations in dissolved oxygen levels in water bodies. During daylight hours, algae photosynthesize and release oxygen, increasing dissolved oxygen levels. However, at night or when algae die and decay, they consume oxygen through the process of decomposition, which can lead to a decrease in dissolved oxygen levels, potentially creating hypoxic conditions for aquatic organisms.
Why is algae growth bad?
Too much algae can reduce oxygen in water. This can cause many fish to die.
How do phosphates affect oxygen levels in water?
Phosphates can lead to excessive algal growth in water bodies, a process known as eutrophication. As the algae proliferate and die, they are decomposed by bacteria that consume oxygen, leading to lower oxygen levels in the water. This decrease in oxygen can harm fish and other aquatic organisms.
How does algae affect living things?
algae creates more than 75% of the worlds oxygen; without algae no it would be harder to breathe cause people to pretty much die because of the lack of oxygen
How does fertilizer running into a pond lower the oxygen level?
The fertilizer causes an increase in algae. As algae die and are decomposed the decomposers increase and use up all of the oxygen in the water.
When algae die they use up all the in a lake?
they use up all the oxygen.
How can too much nutrients be pollution in water?
Nutrients in lakes can cause eutrophication. What happens is that the nutrients cause the algae to grow excessively. As it dies, bacteria consume it using up large amounts of oxygen dissolved in the water. Aquatic creatures that rely on dissolved oxygen (fish) die.
How does an algal bloom affects the oxygen levels in a lake ecosystem?
An algal bloom can lead to decreased oxygen levels in a lake ecosystem through a process called eutrophication. As the algae die and decompose, bacteria consume oxygen during the decomposition process, depleting oxygen levels in the water. This decrease in oxygen can harm aquatic organisms that rely on oxygen to survive, resulting in fish kills and disruptions to the ecosystem.
What is a area of the ocean with very low oxygen levels?
An area of the ocean with very low oxygen levels is called a "dead zone." Dead zones are often caused by excessive nutrient runoff from land, which leads to algal blooms. When these algae die and decompose, they consume oxygen in the water, creating hypoxic conditions that can be harmful to marine life.
How can algae die?
Algae can die due to environmental stressors like changes in temperature, pollutants, lack of sunlight, or lack of nutrients. Additionally, competition with other algae species or grazing by herbivores can lead to the death of algae.
Why fishes die when there is an algae bloom?
Fish can die during an algae bloom due to a decrease in oxygen levels in the water. Algae blooms can deplete oxygen as they decay, leading to hypoxia or even anoxia in the water, which can suffocate fish. Additionally, some algal species can produce toxins that are harmful to fish and other aquatic life.
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.
