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.
Algal bloom is nothing but the excessive growth of algae on the surface of water it affects the life of the underwater organism as it takes up the oxygen content from the water body and as a result the underwater species die due to the lack of oxygen.
The algal blooms cause algae to grow very fast which promotes bacteria growth. The bacteria then use up all the nutrients/resources (like oxygen) needed for organisms to live. Eventually the organisms will all die.
When an algae bloom occurs it is sometimes caused by an increase in the amount of phosphorous and nitrogen run off from nearby farmland, or pollution such as from sewage or industrial. This is caled eutrophication. http://en.wikipedia.org/wiki/Eutrophication
This nutrient is normally only available in very small amounts, and so the lack of it limits the amount of algae that may grow.... algae needs sunlight and nutrients, since it gets lots of sunlight at the top of the lake once you add a bunch of nutrients.... booom you get an algae bloom.
Now algae does not live very long, and so the top layer dies and sinks to the bottom and the next layer forms on the top of the lake.
First of all the algae layer on the top of the lake is cutting off the light from the plants bellow it.
Second, the death of the algae induced decomposition. Decomposition involves the removal of oxygen from the water.
The lack of oxygen is very bad for all living creates within the lake that require oxygen, such as fish.
If the nutrients suppling the lake are stopped... and the algae dies back, you are left with a clear lake, with no life in it.
Some algae are also known to create toxin as a byproduct which are determintal to orgainsms

Algal blooms, if they become very large, can deplete the oxygen in the water causing the organisms in the water to die. Also, some algaes, especially red ones, are poisonous. So even if the bloom is not large, they will poison the fish and the creatures in the sea. If people eat these poison contaminated fish, they can suffer irreversible brain damage.

Waterborne pollutants can harm aquatic life by disrupting their physiological functions, such as respiration, reproduction, and growth. These pollutants can also accumulate in the tissues of aquatic organisms, leading to long-term health effects and even death. Additionally, waterborne pollutants can cause disruptions in the food chain, ultimately affecting the entire ecosystem.
aqua means water and when u say aquatic you mean water like ecosystem with diff.types of algeas,protist,plankton,and more.
It is an inverse relationship

The final stage of aquatic succession is a land ecosystem
Eutrophication is a process where a body of water becomes overly enriched with nutrients, leading to excessive growth of algae and other aquatic plants. This can result in oxygen depletion and harm to aquatic life, disrupting the ecosystem balance.
An aquatic ecosystem is based on water, and a terrestrial ecosystem is based on land.
A decrease in sunlight can reduce photosynthesis in aquatic plants, leading to decreased plant growth. This can impact the availability of food and habitat for other organisms in the pond ecosystem, potentially causing a decline in biodiversity and disrupting the balance of the ecosystem.
An aquatic ecosystem is an ecosystem located in bodies of water. Types of aquatic ecosystems are The Marine Ecosystem and The Freshwater Ecosystem.

Yes it can.
What does the word diversty mean when you are talking about an aquatic ecosystem?
Fertilizers can lead to nutrient runoff which can result in eutrophication of water bodies, disrupting the balance of aquatic ecosystems. Additionally, excessive fertilizer use can lead to soil and water pollution, harming wildlife and plant species in the ecosystem. Improper use of fertilizers can also contribute to greenhouse gas emissions and contribute to climate change.
