What is the economic importance of green algae?
Mahal ko si cornelio i love you sana mahalin mo rin ako yan ang sagot ko!!!!!!!!!!!!!!!!!
What are the economic importance of spirogyra?
Spirogyra is commonly referred to as green algae. Its economic importance's include the production of organic matter for agriculture, use as a food product, and use in decontamination.
What is the economic importance of protozoans?
Since some types of protozoans (namely plankton) are "considered by some to be the most important organisms on Earth"*, the economic importance, while maybe difficult to measure, would seem to be quite large. *see following text for a discussion: Protozoans are unicellular microbes whose cells have membrane-bound nuclei. In the 21st century, the tendency has been to classify algae outside the class of protozoans. This then would preclude kelp (a type of brown algae) from the class of protozoans. Another possible, widely-used, microorganism that might be confused with protozoa are diatoms--diatomaceous earth, for example, is a valued product (and therefore of great economic importance) made from diatoms. Unicellular aquatic Protista (plankton) form a very important component of the food chain. The photosynthetic ones are called phytoplankton and the heterotrophic ones are called zooplankton (which also includes many animal larvae or tiny crustaceans). The planktons are credited with supporting the lower end of the ocean food chains. They are therefore considered by some to be the most important organisms on Earth. (General info on protozoa: Most protozoa are too small to be seen with the naked eye-most are around 10-50 μm, but forms up to 0.5 mm exist-but can easily be found under a microscope. Protozoa are ubiquitous throughout aqueous environments and the soil, and play an important role in their ecology. Protozoa occupy a range of trophic levels. As predators upon unicellular or filamentous algae, bacteria, and microfungi, protozoa play a role both as herbivores and as consumers in the decomposer link of the food chain. Protozoa also play a vital role in controlling bacteria population and biomass. As components of the micro- and meiofauna, protozoa are an important food source for microinvertebrates. Thus, the ecological role of protozoa in the transfer of bacterial and algal production to successive trophic levels is important. Protozoa such as the malaria parasites, trypanosomes and leishmania are also important as parasites and symbionts of multicellular animals.) sources: arnica.csustan.edu/boty1050/Protista/protista.htm http://en.wikipedia.org/wiki/Plankton http://en.wikipedia.org/wiki/Protozoa
What may be a drawback to using biofuels as a renewable energy resource?
There are several potential drawbacks. If the biofuel is ethanol, then the entire fuel distribution infrastructure and fleet of vehicle engines need to be changed in order to accomodate ethanol, which is more corrosive than gasoline. Moreover, the fuel needs are so large that replacing gasoline with biofuels requires an immense amount of land, which can compete with farmland for food, particularly of corn is used as the biofuel feedstock. Biofuels made from cellulose (the cell walls of plants) reduces this issue slightly. Biofuel production from algae shows some potential but still faces a number of challenges, particularly related to land and water use.
Interdependence in nature is illustrated by?
Interdependence in nature is illustrated by ecosystems. Living organisms rarely exist alone as illustrated by an ecosystem, in which everything is interconnected. The sun provides the light energy, which primary producers (plants, algae, and photosynthetic prokaryotes) use to synthesize sugars and other organic compounds. These sugars and organic compounds are then used as building material for growth and as fuel for cellular respiration. The organisms in the next trophic levels indirectly or directly depend on this photosynthetic output of the primary producers as this chemical energy is then consumed by primary consumers (herbivores), secondary consumers (carnivores), and tertiary consumers (carnivores that eat other carnivores). Many of these nutrient transfers through the trophic level lead to detritus, non living organic material, which provides energy for the detritivores (prokaryotes and fungi) who help to decompose this organic material in an ecosystem. The chemical elements are then transferred in inorganic forms to abiotic reservoirs such as soil, water, and air, which the primary producers recycle into organic compounds. These living organisms are so interconnected that there would be serious consequences for the ecosystem and the living organisms in it if even one trophic level were to be destroyed.
How do cities treat runoff from rain and Snow melt to fight algae blooms?
They put salt on the roads and sidewalks so that there isn't any ice.
Algae blooms are more likely to exist in a?
A lake.
What pollutants are in Chowan river basin?
-Nuisance algae blooms?
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 is potent compound in algae blooms that can quickly paralyze and kill animals?
Anatoxin-a
What is unnatural about algae blooms?
There is nothing unnatural about algal blooms, algae spores float around all over the place and when they land in a place where they can thrive they will. We have to maintain an unnatural balance in pool water in order to stop it from thriving.
Does algae grow faster in dirty water?
Yes, in many cases it leads to algal blooms.
Single celled autotroph cell wall aquatic cause blooms in polluted waters?
algae
Why are saltwater blooms called red tides?
The algae that grow contain red pigments, and they float on the water.
Does the Sea ever appear to be Pink?
yes, during "red tide" which is when a certain species of algae blooms.
What are algal blooms that cause red tide caused from?
Red tide is produced when red algae is reproducing
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.
