How can algal blooms be bad?
Algae blooms are a form of bacteria and can cause skin irritation or respiratory irritation in people who get in the water or handle the algae. Some blooms of blue-green algae can produce chemicals that are toxic to animals and people who drink the untreated water.
Will algae grow faster if you add fertilizer to a pond?
yes, increased nitrates in the water (from the fertiliser), will increase the growth rate of the algae in the pond. this normally depletes the oxygen supply that is naturally in the water, and may lead to the death of small fish and other animals. this occurs from time to time when commercial fertilizers from farming ends up in streams, lakes and ponds - the resultant "algal bloom" can cause a serious imbalance in the ecosystem of the contaminated water body.
What is the main ingredient in fertilizers that can cause algae bloom?
The main ingredient in fertilizers that can cause algae blooms is phosphorus. When excess phosphorus enters bodies of water, it can promote the growth of algae, leading to harmful algal blooms. These blooms can disrupt aquatic ecosystems and deplete oxygen levels in the water, negatively impacting fish and other marine life.
What is it called when too much algae cause water to change color?
algae bloom
What would cause the leaves on a burning bush to yellow and drop?
too much water and or fertilizer,
What can happen after a lake receives a large amount of limiting nutrients?
an algal bloom.
Phosphates and nitrates entering a lake can cause an explosive growth of algae called?
An "algal bloom".
Can humans cause algal bloom in a lake?
Yes. But generally inadvertently, or by accident. There is another class of causation - the willfully ignorant who refuse to accept responsibility for their actions. An excess of phosphate or nitrogen may cause an algal bloom - an overproduction of algae. This algal mat will block light from the water body, and when it eventually dies, it will create an anoxic mat on the lake floor.
What human activity might cause an algal bloom in the lake?
rivers and run- off from farmers fields bring extra nutrients into a lake allow increased growth of algae in the water. The result is a population explosion of algae called an algal bloom
What would happen to the organisms if several house owners fertilize their lawns followed by a big rain?
The fertilizer could cause an algal bloom, which would deplete oxygen in the water and likely make the water toxic. Fish and animals that drink the water are likely to die.
What is the cause of algal bloom?
Extra good growing conditions for that species of alga. Optimal water temperatures, salinity, light, for example.
What problems can algal bloom cause in a lake?
Oxygen Depletion, resulting in a severe drop in some fish species and general unpleasantness
Why do algal bloom occurs?
An increase in nutrients can cause algae growth and reproduction to increase dramatically into a bloom.
What would happen to the organism if several house owners nearby fertilized their lawns followed by a big rain?
The fertilizer could cause an algal bloom, which would deplete oxygen in the water and likely make the water toxic. Fish and animals that drink the water are likely to die.
What causes red tide?
Algal can cause "red tides". Specifically algal blooms.
How does the use of fertiliser damage the environment?
In Australia the use of nitrogenous fertilizers in the Murray-Darling basin has been a cause of some dramatic algal blooms in the slow flowing Darling river. These massive over populations of algae feed on the "second hand" fertilizer and rob the water of oxygen. All water dwelling creatures in the bloom "zones" are affected to the extent that entire fish populations die.
Why are algal blooms dangerous to human health?
Some algae species in blooms produce toxins that can cause illnesses. Some of the toxins can be airborne during a bloom and people can get sick by inhaling the toxins.
