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 are the advantages of coelenterate?
Coelenterates, such as jellyfish, corals, and sea anemones, have several advantages that contribute to their ecological success. Their simple body structure allows for efficient movement and feeding, as they possess specialized cells called cnidocytes for capturing prey. Additionally, many coelenterates have symbiotic relationships with algae, which provide them with energy through photosynthesis, enhancing their survival in nutrient-poor environments. Furthermore, their ability to reproduce both sexually and asexually enables rapid population growth and adaptability to changing conditions.
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.
What are the benefits of using algae-eating snails for ponds?
Algae-eating snails can help maintain a balanced ecosystem in ponds by consuming excess algae, which can improve water quality, reduce algae blooms, and create a healthier environment for fish and other aquatic life.
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.
How is algae harmful to the ecosystem?
Algae can be harmful to the ecosystem by causing algal blooms, which deplete oxygen levels in waterways and harm aquatic life. These blooms can also release toxins that are harmful to other organisms in the ecosystem. Additionally, when algae die and decompose, they can further reduce oxygen levels in the water, leading to dead zones where marine life cannot survive.
What are clusters of algae called?
Clusters of algae are called algal blooms. These blooms can occur when conditions are favorable for algae growth, such as high nutrient levels and warm temperatures. While some algal blooms are harmless, others can produce toxins that can be harmful to aquatic life and humans.
Algae blooms are more likely to exist in a?
A lake.
Does eutrophication directly contribute to the formation and exacerbation of algae blooms in aquatic ecosystems?
Yes, eutrophication directly contributes to the formation and exacerbation of algae blooms in aquatic ecosystems. Eutrophication is the process where excess nutrients, such as nitrogen and phosphorus, enter a body of water, leading to an overgrowth of algae. This overgrowth of algae can result in algae blooms, which can harm aquatic ecosystems by depleting oxygen levels and causing other negative impacts.
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.
What is the effect of humic acid on algae?
Humic acid can act as a chelating agent, binding to metals in the water which are essential for algae growth, thereby limiting their availability to the algae. This can help to inhibit algae growth and reduce algal blooms. Additionally, humic acid can also improve water quality by reducing nutrient levels in the water that algae thrive on.
Does algae grow faster in dirty water?
Yes, in many cases it leads to algal blooms.
What is it called when too much algae cause water to change color?
It is called an algal bloom. Algal blooms can be caused by excess nutrients in the water, such as nitrogen and phosphorus, and can result in the water changing color due to the high concentration of algae. Some algal blooms can be harmful to aquatic ecosystems and human health.
