What is an indicator species How are indicator species used to assess pollution levels?
Indicator species (IS) are animals, plants, or microorganism used to monitor changes in our environment. For example, they can tell us about the impact of pollution on an ecosystem, or how well an impaired environment is being managed or restored.
What are the names of the species used in this experiment which of these species was the most tolerant of increased acidity in the aquarium which species was the least tolerant?
Which of these species was the most tolerant of increased acidity in the aquarium? Which species was the least tolerant? Sideswimmer, aquatic earthworm, crayfish, clam, and snail are the species used for this experiment. Surviving to a ph 4.0 reading, the aquatic earthworm was the most tolerant ofthe species tested.
What is an indicator species?
A species whose status provides information on the overall condition of the ecosystem and of other species in that ecosystem. They reflect the quality and changes in environmental conditions as well as aspects of community composition.

The species used in this experiment were: Craw Fish, Side Swimmer, Dragonfly Nymph, Fairy Shrimp, Aquatic Earthworm, Snail, Tubifleworm, Leech, Clam, and Stonefly Nymph. The most tolerant specie was the Tubiflexworm that had a population of 4, when the ph Level dropped to 3.4.
What material found in marble or limestone can dissolve as a result of contact with acid rain?
calcite
How does acid rain affect ecosystems?
Acid rain leaches aluminum from the soil. That aluminum may be harmful to plants as well as animals. Acid rain also removes minerals and nutrients from the soil that trees need to grow. The trees are then less able to absorb sunlight, which makes them weak and less able to withstand freezing temperatures.
What are the effects of acid rain towards biodiversity?
Acid rain causes a cascade of effects that harm or kill individual fish, reduce population numbers, completely eliminate species from a lake, and decrease biodiversity. As acid rain flows through soils in a watershed, it releases aluminum from soils into the lakes and streams located in that watershed.
What are the different causes of acid rain?
Power plants release the majority of sulfur dioxide and much of the nitrogen oxides when they burn fossil fuels, such as coal, to produce electricity. In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.
Which acid is green in Colour?
Thirty-four percent sulfuric acid. Five percent chromium solution. Zinc sulfide, doped with copper, which gives it its green glow.
Is Acid blue or red?
Litmus. Litmus indicator solution turns red in acidic solutions and blue in alkaline solutions. It turns purple in neutral solutions.
What chemicals are the color green?
Pyrotechnic colorant
| Color | Compound name | Chemical formula |
|---|---|---|
| Green | Barium chlorate | Ba(ClO3)2 |
| Green | Barium carbonate | BaCO3 |
| Green | Barium nitrate | Ba(NO3)2 |
| Green | Barium oxalate | BaC2O4 |
Is green fire hotter than blue?
Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood. For example, the element lithium will produce a pink flame, while the element tungsten will produce a green flame.
What burns with a blue flame?
A blue flame burns the fuel completely producing carbon dioxide, water and heat. The natural gas flame temperature is about 1,960°C. Natural gas burns with a blue flame colour, with complete combustion. LPG (propane) also burns with a blue flame colour.
What is the hottest color of fire?
While blue represents cooler colors to most, it is the opposite in fires, meaning they are the hottest flames. When all flame colors combine, the color is white-blue which is the hottest. Most fires are the result of a chemical reaction between a fuel and oxygen called combustion.
