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.

Why algal blooms occur?
Fertilize runoff
What are herbivores of the ocean?
There are several herbivores in the ocean most of the are called bottom feeders, like plankton and shrimp.
Lumps of minerals on the ocean floor are called?
Nodules...
What event's typically contribute to an algal bloom in a lake or an ocean?
In fresh water radical changes in PH balance. It can be due to pollution in freshwater environments where stagnant water provides a good habitat for algae and acidic pollutants encourage growth. Red tides are not due to pollution though. They are caused by natural changes in salinity, temperature and nutrient levels that allow Karenia brevis algae, the culprit behind red tides, to grow exponentially. It's still not fully understood what causes such increases but many theories regard high temperature, a lack of wind and rainfall as major factors.
Why are ocean fossils found on top of Rocky Mountains?
Obviously the soil and rocks that are now on top of the mountain were once underneath the ocean. This occurs when the ground is raised up from beneath the sea by plates colliding and raising mountains.
What occurs during an algal bloom?
algal blooms come with currents of the ocean. they have seasons, or time of year that they actually bloom. algal blooms are known to kill whales while they come up for air, because of the concentration of their "food" getting into their lungs and suffecating them.
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 causes increase of algal bloom?
Detergents and fertilizers that go to the rivers and lakes pollutes the water and fertilize the water, causing an algal bloom or overgrowth of water plants.
Does the oceans annual algae bloom peoduce nore oxygen than all rainforests combined?
The ocean's annual algal bloom does not produce more oxygen than all rainforests combined, quite the contrary, it tends to deplete the available oxygen in the water.
Why algal blooms occur?
Fertilize runoff
How tall is Ocean Bloom?
Ocean Bloom is 5' 4".
What zonation occurs in the ocean zone called the?
Zonation occurs in the ocean zone called the intertidal. Zonation is the distribution of organisms in biogeographic zones. It is also the arrangement or formation in zones.
When was Ocean Bloom born?
Ocean Bloom was born on November 18, 1977, in Vancouver, British Columbia, Canada.
Zonation occurs in the ocean zone called the?
Zonation occurs in the ocean zone called the intertidal. Zonation is the distribution of organisms in biogeographic zones. It is also the arrangement or formation in zones.
What are alga blooms?
Algae blooms are when too much of a pollutant enters a waterway and choke plants and algae grows rapidly.Or people say it as overfed plants can grow so quickly that they choke waterways. Whenoverfed, algae also reproduce rapidly that is called a algae bloom.
What types of climate that occurs in coastal area along the Arctic Ocean?
It is called a tundra.
What is you it called when volcanic activity occurs along mid-ocean ridge in large cracks?
it is called rift valleys
