5 Matching Questions

  1. Humus (1)
  2. Biogeochemical Cycle (1)
  3. Ecotone (1)
  4. Biome (1)
  5. Sulfur Cycle (1)
  1. a Climatically and geographically defined as similar climatic conditions on earth and often referred to as "ecosystems" (ex. Tundra, tropical rain forest, and Taiga).
  2. b A transition area between two adjacent but different plant communities (ex. reed beds tend to accumulate organic matter which is then colonized by trees, forcing the reeds further into the lake).
  3. c 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).
  4. d One of the constitutes of many proteins, vitamins, and hormones, and it recycles throughout the earth also in a Biogeochemical cycle (ex. mineralization of organic sulfur to the inorganic form, hydrogen sulfide: (H2S))
  5. e 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 Multiple Choice Questions

  1. A group of interacting species sharing a populated environment (ex. human communities, plant communities, and animal communities)
  2. Graphical representation designed to show the biomass productivity at each trophic level in a given ecosystem (sig. helps discover the amount of energy distributed within each given trophic level).
  3. 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).
  4. A consumer in which consumes the consumer of the plants or autotrophs (ex. foxes, owls, and snakes).
  5. 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%).

5 True/False Questions

  1. Nitrogen Fixation (2)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%).

          

  2. Limiting Factor (1)The extraction of certain materials from a carrier into a liquid (ex. agriculture leaching, chemical science leaching, and pedology leaching).

          

  3. Species (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)

          

  4. Biotic Potential (2)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)

          

  5. Ecological Efficiency (1)The continuous movement of water on, above, or below the surface of earth (sig. Water cycle involves the exchange of heat energy, which can also lead to temperature changes).
