5 Matching Questions

  1. Leaching (1)
  2. Nitrogen Cycle (1)
  3. Lithosphere (1)
  4. Percolation (3)
  5. Humus (1)
  1. a The rigid outtermost shell of a rocky planet (ex. Earth consists of a crust and uppermost mantle within it's lithosphere.
  2. b The process by which nitrogen is converted between ammonia acids (sig. Scientists use the nitrogen cycle to determine the total amount of Nitrogen on Earth, which amounts to about 79%).
  3. c The extraction of certain materials from a carrier into a liquid (ex. agriculture leaching, chemical science leaching, and pedology leaching).
  4. d Any organic matter which has reached a point of stability where it will not break down any further and remain as it is for centuries (ex. mature compost and natural compost used to amend soil).
  5. e 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).

5 Multiple Choice Questions

  1. Non-living chemical or physical factors within the environment (ex. radiation, temperature, and water).
  2. A biological environment consisting of all the organisms living in a particular area as well as non-living components interact with the organisms as well (ex. terrestrial ecosystem, aquatic ecosystem, and artificial ecosystem).
  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. Climatically and geographically defined as similar climatic conditions on earth and often referred to as "ecosystems" (ex. Tundra, tropical rain forest, and Taiga).
  5. A renewable energy source in which a biological material is from living or recently deceased organisms (ex. garbage, wood, waste, landfill gasses, and alcohol fuels).

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. Porosity (1)A group of interacting species sharing a populated environment (ex. human communities, plant communities, and animal communities)


  3. Biosphere (1)The global sum of all the ecosystems together, often referred to as the "zone of life of earth" (sig. Thought to evolved from through a process of biogenesis or biopoesis over 3.5 billion ago).


  4. Ecological Efficiency (1)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. Aquatic Life Zone (1)The total number of genetic characteristics in the genetic makeup of a species (sig. Plays a large role in survival and adaptability of species due to the change of the species environment, slight gene variations are necessary to change an organisms anatomy to survive).
