vocab & definintions for BGC and ecosystems

ORGANIC anything relating to a living organism that contains Carbon
LIMESTONE sedimentary rock made from minerals that contain Carbon
EROSION occurs when flowing wind or water degrade soil or rock
RESPIRATION release of carbon dioxide into the atmosphere by living organisms
PHOTOSYNTHESIS plants convert carbon dioxide from the atmosphere into food using light energy
COMBUSTION organic material is burned and carbon dioxide/carbon monoxide is released
FOSSIL FUELS organic materials that release carbon dioxide when burned
DECOMPOSITION process of 'rotting' where tissue is broken down, but minerals remain
GREENHOUSE GASES waste materials in the atmosphere that absorb radiation from the sun
ASSIMILATION conversion of absorbed nutrients (like nitrogen) into the cells of an organism
NITROGEN FIXATION process of combining nitrogen gas with hydrogen to form ammonia
AMMONIFICATION how bacteria can form ammonia through the decomposition of organic matter
DENITRIFICATION process of releasing nitrogen from the soil through the action of bacteria
URIC ACID / UREA nitrogen-containing waste found in urine of most animals
AMMONIA compound of nitrogen and hydrogen made by bacteria from decomposing organic matter
NITRATES derivatives of nitric acid containing Nitrogen and Oxygen (NO3)
DECOMPOSITION process of 'rotting' where tissue is broken down, but minerals remain
BACTERIA prokaryotic, unicellular organisms involved in nitrogen fixation
GROUND WATER water that has soaked through the surface into the soil - springs or wells
RUNOFF rainfall that doesn't soak into, but flows off the ground's surface
EVAPORATION water changing from a liquid state into a vapor or gas
CONDENSATION the physical change of water from its gaseous form to a liquid or solid
TRANSPIRATION water directly transferred from plants to atmosphere through tiny pores in leaves
PRECIPITATION condensed water falling from atmosphere to the surface of earth
PERCOLATION seeping of groundwater through holes in soil or permeable rock
SURFACE WATER water collecting on top of the ground in streams, rivers, lakes, oceans
AQUIFERS underground bodies of water found in permeable rock

ABIOTIC another term for non-living things...
DECOMPOSITION process of breaking down dead organism to release CO2 into the atmosphere
DECOMPOSERS organisms that break down dead/decaying organisms from all trophic levels
RUNOFF describes water that flows on the surface toward lakes, rivers, and oceans
FOOD WEB diagram representing feeding interactions between trophic levels in a community
DETRITIVORES these organisms eat dead animals they find in the environment
OMNIVORES these organisms eat both producers and consumers from all other trophic levels
RESPIRATION exchange of gases which releases CO2 into the atmosphere
MATTER has mass and takes up space; can be cycled in communities
BIOTIC living things are said to be this…
CONSUMERS must get their energy from other organisms
CONDENSATION occurs when water forms into tiny droplets from its gaseous state
PRODUCERS organisms able to bring energy into communities by harnessing light energy
CARNIVORES organisms that eat only other animals
TROPHIC LEVEL part of a food chain or food web that identifies where an organism gets its energy
ECOLOGY study of organisms interacting with each other/environment
HABITAT the location in which a specific organism lives is called its...
PERCOLATION this occurs when water seeps through the soil into aquifers
HERBIVORES type of organisms that eat only plants
PHOTOSYNTHESIS use of sunlight to produce sugars from CO2 in the atmosphere
EVAPORATION water entering the atmosphere as a gas
SURFACE WATER water that collects in streams/ponds at the earth’s surface
PRECIPITATION what it's called when water returns to earth, such as hail or sleet
