Calcuim,Magnesium,potassium, and Sulfur Flashcards
Why they’re important
Calcium,Magnesium,Potassium
Regulating cell processes and in transmitting signals between cells
What material is derived from these
Calcium,Magnesium,Potassium, And Sulfur
Rock and decomposed vegetation
How they can be deposited from the air
Calcium,Magnesium,Potassium, And Sulfur
Ca2+ Mg2+ and k+ can all be deposited from the air in small amounts of dust
Which macronutrients are strongly or weakly attracted
Calcium,Magnesium,Potassium, And Sulfur
Ca2+ and Mg2+ are strongly attracted to soil particles and abundant in many soils overlying these types of rocks
K+ is weakly attracted to soil particles and more susceptible to being leached away by water moving through the soil
1
Calcium,Magnesium,Potassium, And Sulfur
Most sulfur exists in rocks and is released into soils and water as the rocks weather overtime
Sulfurs importance
Calcium,Magnesium,Potassium, And Sulfur
Plays a role in allowing organisms to use oxygen
2
Calcium,Magnesium,Potassium, And Sulfur
Producers absorb sulfur through their roots and form sulfate ions SO2-
4
And the sulfur cycles through the food web
What cycle has a gaseous component
Calcium,Magnesium,Potassium, And Sulfur
Sulfur
Source of atmospheric sulfur Calcium,Magnesium,Potassium, And Sulfur
Volcanic eruptions are a natural source of atmospheric sulfur in the form of sulfur dioxide (SO2)
How Sulfur dioxide is added to the atmosphere
Calcium,Magnesium,Potassium, And Sulfur
Burning fossil fuels, mining of metals like copper
Sulfur is converted into what when it mixes with the water Calcium,Magnesium,Potassium, And Sulfur
Sulfur acid (H2SO4)
How can sulfuric acid be carried back to earth Calcium,Magnesium,Potassium, And Sulfur
Rain or snow
As humans add more sulfuric dioxide we cause more what Calcium,Magnesium,Potassium, And Sulfur
Acid precipitation which can negatively affect terrestrial and aquatic ecosystems
