5 Matching questions

  1. Ecological Efficiency (1)
  2. Nitrogen Fixation (2)
  3. Soil Texture (2)
  4. Range of Tolerance (1)
  5. Carbon Cycle (1)
  1. a The Biogeochemical cycle of which carbon is exchanged throughout the biosphere, pedosphere, geosphere, hydrosphere, and the atmosphere (sig. Helps scientific researches discover where large amounts of carbon are stored i.e. the ocean contains the largest active pool of carbon near the surface of earth).
  2. b A soil property used to describe the relative proportion of different grain sizes of mineral particles in the soil (ex. clay, silt, sand, and loam).
  3. c The range of conditions in which an organism can survive and thrive (sig. can mathematically predict the amount of a population with given standards in an ecosystem).
  4. d The efficiency with which energy is transfered from one trophic level to another (ex. 20 units of energy are produced are trophic level 1; one half of that is lost to non-predatory death, while the other half is ingested by trophic level 2; one half of the amount ingested is expelled through defecation while the other half is ingested by trophic level 3).
  5. e The natural process by which nitrogen in the universe is converted to ammonia (ex. used by many prokaryotes including bacteria and actinobacteria).

5 Multiple choice questions

  1. The maximum reproductive capacity of a population, if resources are limited (sig. If the value of population increase can be determined, the impact of the environment upon the population can also be determined)
  2. The movement and filtering of fluids through porous materials (ex. coffee percolation, the solvent being water, permeable substances being coffee grounds, and soluble constitutes are the objects that give coffee taste and color).
  3. Representations of predator-prey relationships between species within an ecosystem or habitat (ex. A snakes prey might be a mouse, while his predator may be a badger that is represented through a web of organisms).
  4. A pathway by which a chemical element or molecules travels throughout biotic and abiotic components on earth (ex. carbon cycle, nitrogen cycle, and water cycle).
  5. The extraction of certain materials from a carrier into a liquid (ex. agriculture leaching, chemical science leaching, and pedology leaching).

5 True/False questions

  1. Scavenger (1)One of the basic units of biological classification and taxonomic rank, one of a group of organisms capable of breeding and producing fertile offspring (ex. generic name and specific name, Boa Constrictor)

          

  2. Anaerobic Respiration (2)The release of energy from glucose or another organic substrate in the presence of Oxygen (ex. takes place in most living things: to get rid of Carbon Dioxide and excess water this is excretion and maximum energy is released from glucose).

          

  3. Law of Tolerance (2)The existence, abundance, and distribution of species depends on the tolerance level of each species to physical and chemical factors (ex. In aquatic ecosystems, major limiting factors include pH, the amount of dissolved oxygen in the water and the salinity).

          

  4. Soil Horizons (1)Specific layer in the land area that is parallel to the soil surface that possesses physical characteristics which differ from the layer above and beneath (ex. alluvium, sand dunes, and volcanic ash).

          

  5. Abiotic(1)Relating to, produced by, or caused by living organisms (ex. wood, linoleum, straw, humus and crude oil).
