5 Matching questions

  1. Ecosystem (1)
  2. Genetic Diversity (1)
  3. Biogeochemical Cycle (1)
  4. Anaerobic Respiration (2)
  5. Hydrologic Cycle (1)
  1. a 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).
  2. b A way for an organism to produce usable energy in the form of ATP without the presence of Oxygen (ex. glucose + 3NO3- + 3H2O 6HCO3- + 3NH4+, ΔG0' = -1796 kJ) (
  3. c 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).
  4. d 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).
  5. e 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).

5 Multiple choice questions

  1. 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. The combined mass of water found on, under, and above the planet Earth (ex. the total mass of the Earth's hydrosphere is about 1.4 x 10^18 tons).
  3. 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)
  4. 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).
  5. Any product of condensation of atmospheric water vapor that falls under gravity (ex. rain, snow, sleet, hail, and graupel).

5 True/False questions

  1. Aquatic Life Zone (1)Zones under the water where aquatic life is present which can be characterized by aquatic ecosystems (ex. marine ecosystem and freshwater ecosystem).


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


  4. Limiting Factor (1)A factor that controls a process such as an organisms growth or species population, size or distribution (ex. sunlight in a rainforest).


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