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.
Will algae grow in a dark cool place?
Most microalgae grow through photosynthesis - by converting sunlight, CO2 and a few nutrients, including nitrogen and phosphorous, into material known as biomass This is called "autotrophic" growth. Other algae can grow in the dark using sugar or starch (called "heterotrophic" growth), or even combine both growth modes (called "mixotrophic" growth).
Population explosion of poisonous red algae along ocean shorelines?
Several factors contribute to the overpopulation of algae which include variances in water temperature and sunlight, oxygen content in the water can speed up growth especially if levels are higher than normal and the abundance of nutrients such as phosphates, nitrates and ammonia can increase algae population.
How do sponges die?
Sponges can die if they are exposed to air, starved, improperly placed, or experience algae overgrowth. The will also die, or course, if they are eaten by a predator.
What can cause excess growth of algae in water?
Algae is caused by the change of nutrients in the water.
What does too many nutrients in a marine tank do?
Excess of nutrients causes eutrophication i.e. excessive growth of algae take place leading to oxygen deficiency.
What is a green film of algae in a fish tank signals?
Green algae overgrowth in a tank signals many things. It could mean there is too much direct sunlight or lamps on in the tank. It's possible that the water has too mush nutrients, due to accidental overfeeding. The list goes on.
Fertilizers can put extra nitrogen into coastal waters which can cause?
overgrowth of algae that produce toxins
Can algae make a relationship with fungi on ground and how?
fungi and algae can grow together and produce substabnce called lichen, on the surface of the rocks. fungus provide algae with protection, whereas algae provide fungus with nutrients.
Is red tide cells red blood cells?
No. The red tide is caused by an overgrowth of a type of algae.
What is the niche of algae?
Algae is a producer of oxygen and a sink for carbon dioxide. They remove excess nutrients from the water. They also provide shade and a place to nest if there is a big clump of it. Algae is often eaten by other organisms in the water. :)
How does green algae eat?
Green algae eats by sucking in nutrients
How green algae eat?
Green algae eats by sucking in nutrients
How does algae get water and nutrients?
Algae gets its nutrients from sunlight and water from the water itself that it's in, because algae only grows in water.
What are the effects of stagnant water?
Stagnant water usually has a lack of oxygen and an excess of nutrients, which causes excessive algae growth.
Are you willing to eat edible algae?
The reason some algae is called edible algae is that it is safe to eat. It is an excellent source of many nutrients. Many people like the taste and are willing to eat it, but some say that edible algae is too bitter.
