THE PASSWORD TO EDIT THE SET IS Cheney

element

pure chemical substance made up of same atoms

biodiversity

variety of organisms in an ecosystem. Indicator of the health of an ecosystem.

abiotic

nonliving, physical features of the environment, including air, water, sunlight, soil, temperature, and climate

fossil fuels

coal, oil, natural gas, and other fuels that are ancient remains of plants and animals. Hydrocarbon

solubility

the ability to dissolve in another substance

photosynthesis

process by which plants use the sun's energy to convert water and carbon dioxide into sugars

calcium carbonate

CaCO3 - shells, limestone

carbon cycle

biogeochemical cycle that describes transformation of these compounds in nature CaCO3, CO2, HCO3−, CH4, R-CH3

nitrogen cycle

biogeochemical cycle that describes the transformation of these compounds in nature N2, NH4+, NH3, NO2-, NO3, R-NH2

pH

measure of the concentration of H+, power of Hydrogen

chemical formula

notation that shows what elements a compound contains and the ratio of atoms or ions in the compound

biogeochemical cycle

A pathway by which a chemical elements moves through both living and non-living components of an ecosystem

oxygen

O2, diatomic molecule which composes 21% of dry air

carbon dioxide

CO2, colorless, odorless gas, produced by burning carbon and organic compounds and by respiration and absorbed by plants in photosynthesis.

bicarbonate ion

HCO3-, decreases pH of environment

methane

CH4, odorless flammable gas that is the main constituent of natural gas

carbohydrate

CH2O, common names sugar and starches. Form of chemical energy for cells, broken down into glucose

atmospheric nitrogen

N2, diatomic molecule which composes 78% of dry air

ammonia

NH3, A colorless gas with a characteristic pungent smell. It dissolves in water to form a strong base solution.

nitrates

NO3-, compound used by plants for nutrients

protein

R-NH2, large biomolecue made of amino acids and used as structural material for cells

combustion

process of burning, producing heat and light

assimilation

building living tissue

nitrogen fixation

process which bacteria convert atmospheric nitrogen to usable forms for plants
