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 problems can algal bloom cause in a lake?
Algal blooms in a lake can lead to reduced oxygen levels and block sunlight from reaching underwater plants, harming fish and other aquatic life. The rapid growth of algae can also release toxins, causing water contamination and potential health risks for humans and animals.
Can you summarize the role of algal blooms in disrupting the equilibrium in an aquatic ecosystem?
An algal bloom or marine bloom or water bloom is a rapid increase in the population of algae in an aquatic system. Algal blooms may occur in freshwater as well as marine environments. Typically only one or a few phytoplankton species are involved and some blooms may be recognized by discoloration of the water resulting from the high density of pigmented cells. Although there is no officially recognized threshold level, algae can be considered to be blooming at concentrations of hundreds to thousands of cells per milliliter, depending on the causative species. Algal bloom concentrations may reach millions of cells per milliliter. Colors observed are green, yellowish-brown, or red. Bright green blooms may also occur. These are a result of blue-green algae, which are actually bacteria (cyanobacteria). Some algal blooms are the result of an excess of nutrients (particularly phosphorus and nitrogen) into waters and higher concentrations of these nutrients in water cause increased growth of algae and green plants. As more algae and plants grow, others die. This dead organic matter becomes food for bacteria that decompose it. With more food available, the bacteria increase in number and use up the dissolved oxygen in the water. When the dissolved oxygen content decreases, many fish and aquatic insects cannot survive. This results in a dead area.
Lake that has a large amount of plant growth due to nutrients?
The lake is likely experiencing eutrophication, where excess nutrients like nitrogen and phosphorus are present, leading to increased plant growth. This can result in algal blooms, reduced oxygen levels, and negative impacts on aquatic life. Efforts to reduce nutrient inputs, such as from agriculture or sewage, are important to restore the lake's ecological balance.
What abiotic factor is changing the ecosystem of Lake Washington and how has this factor changed over time?
One major abiotic factor affecting Lake Washington is nutrient pollution, particularly from urban runoff and sewage. Over time, nutrient levels in the lake have fluctuated due to changes in land use practices and pollution control measures. Elevated nutrient levels can lead to algal blooms, reduced water quality, and disruptions to the ecosystem.
What is the major issue concerning the well-being of the Mono Lake ecosystem?
The major issue concerning the well-being of the Mono Lake ecosystem is that some humans are draining the lake for the water. This is a big problem. If the humans stop taking the water there is not enough water for them. But if they keep on taking the water there will be not water left to substance the Mono Lake Ecosystem. But human beings have not found out how much that the lake need to substance an ecosystem.
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".
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 events typically contribute to an algal bloom in a lake or an ocean?
A decrease in the populations of the things that eat the thingies.
What problems can algal bloom cause in a lake?
Algal blooms in a lake can lead to reduced oxygen levels and block sunlight from reaching underwater plants, harming fish and other aquatic life. The rapid growth of algae can also release toxins, causing water contamination and potential health risks for humans and animals.
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.
How could an algae bloom cause problem to the lake ecosystem?
it kills animals in the water.
What can happen after a lake recives a large input of a limiting nutrient?
After a lake receives a large input of a limiting nutrient such as phosphorus or nitrogen, excessive algal growth can occur. This can lead to algal blooms which deplete oxygen levels in the water, harm aquatic life, and disrupt the ecosystem balance. Additionally, the increased algal growth can lead to a phenomenon known as eutrophication, where the lake becomes overly enriched with nutrients and can become turbid and inhospitable to many organisms.
Are algae found in Lake Michigan?
Yes, algae are found in Lake Michigan. They are an essential part of the lake's ecosystem, providing food and oxygen for other organisms. However, excessive algal growth can lead to water quality issues such as harmful algal blooms.
What is Lake color?
Lake color can tell you many things about the water body, like nutrient load, algal growth, and water quality
How can algal blooms be harmful to aquatic life?
because euglenophytes absorb waste and such... they recycle it and so!.. when theres to much waste the euglenophytes make things called "algal blooms" the algal blooms deplete the waters nutruents and oxygen killing algae and other organisms
Why is eutrophication bad?
Natural eutrophication isn't as much of a problem as artificial eutrophication. Artificial eutrophication is caused by humans (fertilizer from farms, lawns, gardens, etc. pesticides, herbicides, road chemicals, etc) these chemicals cause eutrophication to happen much faster than it should. If eutrophication happens faster, algal blooms (large floating mats of algae) form. When algal blooms decay, the bacteria that decays it depletes the oxygen in the lake or pond and the fish die of suffocation.
