5 Matching Questions

  1. Pyramid of Energy Flow (1)
  2. Law of Tolerance (2)
  3. Biotic(1)
  4. Ecosystem (1)
  5. Ecotone (1)
  1. a Relating to, produced by, or caused by living organisms (ex. wood, linoleum, straw, humus and crude oil).
  2. b 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).
  3. c 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).
  4. d 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).
  5. e 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 Multiple Choice Questions

  1. 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. 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).
  3. The extraction of certain materials from a carrier into a liquid (ex. agriculture leaching, chemical science leaching, and pedology leaching).
  4. 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).
  5. 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).

5 True/False Questions

  1. Chemosynthesis (3)The process that converts carbon dioxide into organic compounds using the energy from sunlight (ex. process always begins when energy from light is absorbed by proteins that contain chlorophylls).

          

  2. Trophic Levels (1)An organism and the position it occupies on the food chain (ex. primary producers level 1 and predators at level 3).

          

  3. Primary Consumer (1)A consumer in which consumes the consumer of the plants or autotrophs (ex. foxes, owls, and snakes).

          

  4. Photosynthesis (2)The process that converts carbon dioxide into organic compounds using the energy from sunlight (ex. process always begins when energy from light is absorbed by proteins that contain chlorophylls).

          

  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).
