  2. WhatistheNutrientCycle? • In biology, the nutrient cycle is a concept that describes how nutrients move from the physical environment into living organisms, and subsequently are recycled back to the physical environment.

  3. What are micronutrients? • Micronutrients are nutrients required by humans and other organisms throughout life in small quantities.

  4. Macronutrients • Macronutrients are nutrients required by humans and other organisms throughout life but in big quantities.

  5. Whatis a limitingnutrient? • A limiting factor or limiting resource is a factor that controls a process, such as organism growth or species population, size, or distribution.

  6. Carnivores Herbivores Plants Nutrients

  7. How does nutrient availability relate to the primary productivity of an ecosystem? • Thisterm, isbasedonthebottom-top model.

  8. Whyisntcarbonaddedtoplantfertilizers? • Carbonisnot a nutrientsforplantsallcarbon use byplantstoformsugar, stratches, cellulouse, etc.

  9. Whichisthetypicalseawaterlimitingnutrient? • nitrogen is the main limiting nutrient in saltwater environments.

  10. Whichisthetypicalfreshwaterlimitingnutrient? • ThetypicallimitingnutrientisPhosphorus(P).

  11. Howisfertilizerrunoffrelatedtoalgalbloom? • Fertilizer contains nutrients that help crops grow, but not all of the nutrients (like nitrogen and phosphorus) are used by the crops. The ground water collects these leftover nutrients and carries them into large water bodies, these ecosystems have a natural equilibrium.

  12. Lake Water-QualityClassification

  13. What do Oligotrophicmean? • (of a lake or pond) having low levels of nutrients and high levels of dissolved oxygen.

  14. WhatsdoesMesotrophic mean? • Mesotrophicisa body of water,havinga moderate amount of dissolved nutrients.

  15. WhatsdoesEutrophic mean? • It is a process when a body of water gets an abundant supply of nutrients by excessive organic matters, sewage, or fertilizers and consequently stimulates huge algal growth.

  16. WhatsdoesHypereutrophic mean? • The quantities of nitrogen, phosphorus, and other biologically useful nutrients are the primary determinants of a lake's trophicstate.
