plankton › Definition and Meaning
At the request of the biology termed as plankton to a series of very small, microscopic organisms, which may be of animal origin, zooplankton, or plant, phytoplankton, which are present floating in marine waters and lakes, ie they can be found in salt or fresh water, which are the staple food of higher animalsshould be noted that the phytoplankton is almost always near the water surface because just need daylight for the process to occur photosynthesis, that just involves the conversion of inorganic matter into organic thanks to sunlight, ie, the power light will be transformed into chemical energy.
Meanwhile, unlike the phytoplankton, zooplankton is a movement constant from top to bottom of the water, being able to travel 400 meters; night is coming to the surface to feed and day lies down to cover radiation from the sun.
Plankton species are mostly transparent and can only be seen by looking at them color the microscope. The species found on the surface are reddish while those that are not are bluish. Their average size is less than one millimeter, although there are some larger.
Phytoplankton is food for zooplankton and the latter is the food of crustaceans, fish, among others, during their larval stage.
For its part, it is called red tide to the excessive proliferation of microalgae in estuaries or at sea and which is caused by different types of algae present in a large number indeed. It is called red tide because of the red coloration of the flowers just seem to dye the water red.
Widely favorable conditions such as the temperature, nutrients, water passivity, quality and quantity of light, among others, contribute to its development.
Must be careful because there are toxic phytoplankton that are very dangerous and can cause death of some vertebrates. These toxic phytoplankton are characterized by presenting no coloring are rather colorless.

Fermentation is a process widely used in industry as it allows the transformation of grape juice into wine, the barley beer and carbohydrates in carbon dioxide in order to produce one of the most used products in the world as it is the case of bread.
As indicated above lines, yeasts reproduce so asexual by budding or sprouting and in some cases sexually through spores as ascospores. In the reproduction asexual and when conditions are right, a new bud results from the leavening, while, when you have an adult size will be separated from the mother.
Moreover, also it used the term for any mass which is formed by said mold and which is able to rise and to ferment the body with which it is mixed, as in the case of brewer's yeast.
Among the most popular and widespread yeast the stands Saccharomyces cerevisiae, known as yeast. It is a fungus unicellular as well and is the most recognized because it is the one used to produce wide consumption such as bread, wine and beer.
It noted that the use of this type to produce the aforementioned products is due to the ability to produce ethanol and carbon dioxide in the fermentation process.
Pizza, without going any further, is a extendidísimo food consumption in the world and one of its ingredients with water, wheat flour and salt is yeast. This mixture is baked and once cooked to taste is added tomato sauce and mozzarella cheese.
