Nitrogen and phosphorus are the two key elements found in fertilizers that can lead to algal blooms. When these nutrients enter bodies of water, often through runoff from agricultural fields, they promote excessive growth of algae. This rapid proliferation can deplete oxygen in the water, harming aquatic life and disrupting ecosystems. Algal blooms can also produce toxins that affect water quality and public health.

What is it called when too much algae cause water to change color?
It is called an algal bloom. Algal blooms can be caused by excess nutrients in the water, such as nitrogen and phosphorus, and can result in the water changing color due to the high concentration of algae. Some algal blooms can be harmful to aquatic ecosystems and human health.
What can cause excess growth of algae in water?
Excess growth of algae in water, known as an algal bloom, can be caused by nutrient pollution (such as phosphorus and nitrogen), warm temperatures, sunlight exposure, and calm water conditions that allow algae to grow rapidly. Human activities like agriculture runoff, untreated sewage discharges, and fertilizer use can contribute to nutrient pollution in water bodies, leading to algal blooms.
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.
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 happens when fertilizers are added to fresh water?
When fertilizers are added to fresh water, they can lead to eutrophication, a process where excess nutrients such as nitrogen and phosphorus cause algal blooms. These blooms can decrease oxygen levels in the water, harming aquatic ecosystems and leading to fish kills. Fertilizer runoff into waterways can also contribute to pollution and impact water quality.
What can happen after a lake receives a large amount of limiting nutrients?
an algal bloom.
What substance cause an algal bloom to from?
Excessive nutrients, such as nitrogen and phosphorus, in water bodies can cause algal blooms to form. These nutrients provide excessive food for algae, promoting their rapid growth and reproduction. This can lead to a sudden increase in algal populations, resulting in a bloom.
Phosphates and nitrates entering a lake can cause an explosive growth of algae called?
An "algal bloom".
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 is it called when too much algae cause water to change color?
It is called an algal bloom. Algal blooms can be caused by excess nutrients in the water, such as nitrogen and phosphorus, and can result in the water changing color due to the high concentration of algae. Some algal blooms can be harmful to aquatic ecosystems and human health.
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?
Algal blooms are primarily caused by an excess of nutrients, such as nitrogen and phosphorus, in water bodies. These nutrients can come from sources like agricultural runoff, sewage discharge, and fertilizer use, which create conditions that allow algae to grow rapidly and form blooms. Warm temperatures and calm waters further promote algal growth.
Why do algal bloom occurs?
An increase in nutrients can cause algae growth and reproduction to increase dramatically into a bloom.
How does algal bloom affect a body of water?
An algal bloom can cause harm to a body of water by depleting oxygen levels, blocking sunlight from reaching other aquatic plants, and releasing toxins that may be harmful to fish and other organisms. This can disrupt the ecosystem, leading to fish kills and impacting water quality.
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.
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 can cause excess growth of algae in water?
Excess growth of algae in water, known as an algal bloom, can be caused by nutrient pollution (such as phosphorus and nitrogen), warm temperatures, sunlight exposure, and calm water conditions that allow algae to grow rapidly. Human activities like agriculture runoff, untreated sewage discharges, and fertilizer use can contribute to nutrient pollution in water bodies, leading to algal blooms.
