Lichens lack an outer impermeable layer that would protect them from pollutants. Various species find it impossible to live in regions with high concentrations of sulphur dioxide or heavy metals. Others actually favour high concentrations of nitrogen in the form of ammonia. Therefore, by looking for the presence of lichens in ecosystems scientists can try to understand which pollutants might be present. They might, for example, expect to find a certain lichen in combination with certain rocks, climate patterns and other plants. If the lichen really was there in the ecosystem then the scientists could conclude that the system was free of a certain pollutant.
What else can I help you with?
What is the ecological use of lichens?
Lichens are air pollution indicators.
What are the technology that make use of motion detectors?
technology that makes use of motion detectors
How lichen can help science?
Lichens are great indicators of air quality, as they are sensitive to pollution levels. Scientists can study the presence and health of lichens in an area to assess environmental conditions. Lichens also have unique biological properties that can be studied for potential medicinal or industrial applications.
How do computers help scientists learn more about bacteria?
Because, lazers and detectors can count how much bacteria is in an example . Also, because you can use tools to magnify or describe the bacteria
How can you use the word detectors in a sentence?
I have more then one metal detector , and choose my 2nd in line for quick hunts outta the collection of detectors I have .
How did scientists determine that the Earth's mantle existed?
Scientists used detectors which determined the mantle existed. As well, scientists must hypothesize and theorize what cannot be readily seen, and make determinations based on the evidence that does exist.
What is the use of lichen?
Lichens are air pollution indicators.
What are the differences between photoelectric and ionization smoke detectors?
Photoelectric smoke detectors use a light beam to detect smoke particles, while ionization smoke detectors use radioactive particles to detect smoke. Photoelectric detectors are better at detecting smoldering fires, while ionization detectors are more sensitive to fast-flaming fires.
Did NASA invent smoke detectors?
No, NASA did not invent smoke detectors. Smoke detectors were actually invented by George Andrew Darby in 1902. NASA has, however, improved smoke detectors for use in spacecraft and space stations.
Is it legal in Nevada to sell Radar detectors?
Radar detectors are legal to use in Nevada, but as you stated they are illegal to sell.
What are the differences between ionization and photoelectric smoke detectors?
Ionization smoke detectors use a small amount of radioactive material to ionize the air, while photoelectric smoke detectors use a light beam to detect smoke particles. Ionization detectors are better at detecting fast-flaming fires, while photoelectric detectors are more sensitive to slow-smoldering fires.
What is the side effect of metal detectors?
The side effect of metal detectors is that it prevents the use of weapons and it also prevents violent crimes. The side effect of metal detectors is that it prevents the use of weapons and it also prevents violent crimes.
