Chemicals in the Environment
Process of nutrient uptake that requires energy input and moves nutrients against the concentration gradient.
Active transport
0-6.9
These are nutrients we need large amounts of
Macronutrients
The process plants use to uptake water into their roots
Osmosis
What are 2 sources of gases that cause acid rain?
Rotting organics, volcanoes, cars, factories
Nitrogen, Phosphorus, and Potassium
Neutralization reactions produce these 2 compounds as products
salts and water
Carbon
What is it called when organisms take nutrients in through their mouth and digestive system?
Ingestion
Light green
This method of remediation involves passing exhaust from factories through calcium carbonate before it enters the atmosphere.
Scrubbers
This process of acid rain reduction involves the use of precious metals being reacted with emissions at the point-source of pollution (ie. your car)
Catalytic converters
This organic molecule is used for short-term energy use
carbohydrates
Iron is this kind of nutrient
In a base, blue litmus paper turns what colour?
Blue/doesn't change
This is one of the pollutant compounds that is released by combustion reactions (car exhaust, fossil fuel heating, etc). Causes acid rain
sulfur dioxide, nitrogen oxides, carbon dioxide
What are 2 properties of bases?
Slippery/soapy, bitter, pH of more than 7, react with metals
Proteins are made up of combinations of different types of this unit
Amino acids
This form of passive transport is used to move nutrients from an area of high to low concentration
Diffusion
This nutrient is the building blocks of DNA and RNA
Nucleic acids
The materials that come off farmer's fields is called this
Acids contain this ion
H+
Calcium is considered what kind of nutrient
Inorganic macronutrient
This process breaks down large molecules we eat into smaller ones using water
Hydrolysis
A lake next to a farm has a large algae bloom. What is a reason this could have happened? (be specific!)
Nitrogen or Phosphorus runoff
