words only definitions & notes
  1. nitrify
    convert into nitric acid, nitrous acid, or nitrate, especially with the action of nitrobacteria
    The nitrifying bacteria living in the gravel and in association with the plant roots play a critical role in nutrient cycling; without these microorganisms the whole system would stop functioning.
  2. aquaculture
    raising fish or shellfish or growing water plants for food
    Aquaponics is a bio-integrated system that links recirculating aquaculture with hydroponic vegetable, flower, and/or herb production.
  3. nutrient
    any substance that can be metabolized to give energy
    Aquaponics serves as a model of sustainable food production by following certain principles:
    • The waste products of one biological system serve as nutrients for a second biological system.
  4. sustainable
    capable of being prolonged
    Recent advances by researchers and growers alike have turned aquaponics into a working model of sustainable food production.
  5. nitrite
    the radical -NO2 or any compound containing it
    In turn, the hydroponic beds function as a biofilter — stripping off ammonia, nitrates, nitrites, and phosphorus — so the freshly cleansed water can then be recirculated back into the fish tanks.
  6. microorganism
    any living thing that is too small to be seen with the naked eye
    The nitrifying bacteria living in the gravel and in association with the plant roots play a critical role in nutrient cycling; without these microorganisms the whole system would stop functioning.
  7. biological
    pertaining to life and living things
    Aquaponics serves as a model of sustainable food production by following certain principles:
    • The waste products of one biological system serve as nutrients for a second biological system.
  8. algae
    primitive chlorophyll-containing aquatic organisms
    These nutrients — generated from fish manure, algae, and decomposing fish feed — are contaminants that would otherwise build up to toxic levels in the fish tanks, but instead serve as liquid fertilizer to hydroponically grown plants.
  9. decompose
    break down
    These nutrients — generated from fish manure, algae, and decomposing fish feed — are contaminants that would otherwise build up to toxic levels in the fish tanks, but instead serve as liquid fertilizer to hydroponically grown plants.
  10. phosphorus
    a multivalent nonmetallic element of the nitrogen family that occurs commonly in inorganic phosphate rocks and as organic phosphates in all living cells; is highly reactive and occurs in several allotropic forms
    In turn, the hydroponic beds function as a biofilter — stripping off ammonia, nitrates, nitrites, and phosphorus — so the freshly cleansed water can then be recirculated back into the fish tanks.
  11. toxic
    of or relating to or caused by a poison
    These nutrients — generated from fish manure, algae, and decomposing fish feed — are contaminants that would otherwise build up to toxic levels in the fish tanks, but instead serve as liquid fertilizer to hydroponically grown plants.
  12. nitrate
    any compound containing the nitrate group
    In turn, the hydroponic beds function as a biofilter — stripping off ammonia, nitrates, nitrites, and phosphorus — so the freshly cleansed water can then be recirculated back into the fish tanks.
  13. bacteria
    single-celled organisms that can cause disease
    The nitrifying bacteria living in the gravel and in association with the plant roots play a critical role in nutrient cycling; without these microorganisms the whole system would stop functioning.
  14. ammonia
    a strong-smelling gas compounded of nitrogen and hydrogen
    In turn, the hydroponic beds function as a biofilter — stripping off ammonia, nitrates, nitrites, and phosphorus — so the freshly cleansed water can then be recirculated back into the fish tanks.
  15. liquid
    fluid matter having no fixed shape but a fixed volume
    These nutrients — generated from fish manure, algae, and decomposing fish feed — are contaminants that would otherwise build up to toxic levels in the fish tanks, but instead serve as liquid fertilizer to hydroponically grown plants.
