5 Matching questions

  1. Food Web (1)
  2. Habitat (1)
  3. Species Diversity (1)
  4. Hydrologic Cycle (1)
  5. Limiting Factor (1)
  1. a An ecological or environmental inhabited by a particular species of organism (ex. African elephant habitats spread throughout Africa and Microhabitats)
  2. b 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).
  3. c A factor that controls a process such as an organisms growth or species population, size or distribution (ex. sunlight in a rainforest).
  4. d An index that incorporates the number of species in an area and also their relative abundance (ex. Simpsons Diversity index: D = (n / N)2)
  5. e 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 Multiple choice questions

  1. 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).
  2. A soil composed of sand, silt, and clay in relatively even concentration (ex. sandy loam, silty loam and clay loam).
  3. Organisms that break down dead or decaying organisms that carry out of the process of decomposition (ex. fungi and worms).
  4. A carnivore at the topmost of the food chain that feeds on other carnivores (ex. humans).
  5. 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 True/False questions

  1. 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).


  2. Ecosystem (1)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. Ecotone (1)Organisms that break down dead or decaying organisms that carry out of the process of decomposition (ex. fungi and worms).


  4. Scavenger (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).


  5. 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)
