APES Week 16 Vocabulary Flashcards

5757160212	Algal Bloom	A rapid increase in the algal population of a waterway.	0
5757160213	Ammonification	The process by which fungal and bacterial decomposers break down the organic nitrogen found in dead bodies and waste products and convert it into inorganic ammonium (NH4+).	1
5757160214	Anemia	A deficiency of iron.	2
5757160215	Assimilation	The process by which producers incorporate elements into their tissues.	3
5757160216	Biogeochemical Cycles	The movements of matter within and between ecosystems.	4
5757160217	Denitrification	The conversion of nitrate (NO3-) in a series of steps into the gases nitrous oxide (N2O) and, eventually, nitrogen gas (N2), which is emitted into the atmosphere.	5
5757160218	Evapotranspiration	The combined amount of evaporation and transpiration.	6
5757160219	Famine	The condition in which food insecurity is so extreme that large numbers of deaths occur in a given area over a relatively short period.	7
5757160220	Food insecurity	A condition in which people do not have adequate access to food.	8
5757160221	Food security	A condition in which people have access to sufficient, safe, and nutritious food that meets their dietary needs for an active and healthy life.	9
5757160222	Hydrologic Cycle	The movement of water through the biosphere.	10
5757160223	Hypoxic	Low in oxygen.	11
5757160224	Leaching	The transportation of dissolved molecules through the soil via groundwater.	12
5757160225	Limiting Nutrient	A nutrient required for the growth of an organism but available in a lower quantity than other nutrients.	13
5757160226	Macronutrients	The six key elements that organisms need in relatively large amounts: nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur.	14
5757160227	Malnutrition	Having a diet that lacks the correct balance of proteins, carbohydrates, vitamins, and minerals.	15
5757160228	Mineralization	The process by which fungal and bacterial decomposers break down the organic matter found in dead bodies and waste products and convert it into inorganic compounds.	16
5757160229	Nitrification	The conversion of ammonia (NH4+) into nitrite (NO2-) and then into nitrate (NO3-).	17
5757160230	Nitrogen Fixation	A process by which some organisms can convert nitrogen gas molecules directly into ammonia.	18
5757160231	Overnutrition	Ingestion of too many calories and improper foods.	19
5757160232	Runoff	Water that moves across the land surface and into streams and rivers.	20
5757160233	Transpiration	The release of water from leaves during photosynthesis.	21
