Nutrients
These nutrients act mainly as an energy source for metabolism.
What are carbohydrates?
These substances often taste sour and turn litmus paper red.
What are acids?
What is the process whereby we add calcium carbonate to an acidified body of water in order to neutralize it?
What is liming?
These pollutants accumulate in living organisms over time due to their non-biodegradable nature.
What are persistent pollutants?
pH of the water, turbidity, level of dissolved oxygen, amount of nitrates and phosphates would be considered a(n) _______________ limiting factor.
What is abiotic limiting factor?
These two nutrients is most essential for bone structure, along with phosphorus.
What is calcium and fluorine?
This is a chemical substance that changes color when exposed to acids or bases.
What is an indicator?
This device removes sulfur oxides from industrial smokestacks.
What is a scrubber?
This element depletes the ozone layer when released into the atmosphere.
What are chlorofluorocarbons (CFCs)?
Plastic pollution on Bermuda beaches cannot be pinpointed to a specific one place. We would consider it a ______________.
What is non-point source?
These inorganic substances are essential in small amounts for a healthy diet.
What are minerals?
A reaction between an acid and a base produces water and a mineral salt.
What is neutralization?
The dose of a chemical required to kill 50% of a population is referred to as this.
What is LD50?
Bioindicator species are commonly used to test the health of the lake. When there are more leaches and aquatic worms in the lake, we can assume that the health of the lake is
What is poor quality, or low oxygen content?
This term describes pollutants that become less concentrated in larger amounts of water.
What is dilution?
The primary constituents in fertilizers listed in order are
What is nitrogen, phosphorus, and potassium?
The number on which a hot tub’s pH is recorded as basic range will likely be?
What are 8 to 14?
This phenomenon occurs when excess nitrogen and phosphorus cause algae blooms in water systems.
What is eutrophication?
The harmful environmental impact of DDT is primarily due to this.
What is its persistence in the environment and causing eggshells of top predators to thin and chicks to not hatch?
Washing clothes and fertilizing lawns can lead to an increase in these nutrients in wastewater.
What are nitrogen and phosphorus?
This type of pollutant, such as DDT, does not break down easily and accumulates in the environment.
What is a persistent pollutant?
These components are used in order to prevent incomplete combustion (and waste compounds) in cars that burn fossil fuels?
What are catalytic converters?
This technique uses microorganisms to degrade pollutants at contaminated sites.
What is bioremediation?
When pollutants cause harm to living things when their concentrations become stronger as it moves up the food chain.
What is the biomagnification?
The most practical way to ensure that there is no leachate going into our aquifers.
What are sanitary landfills?
