5 Written questions

5 Matching questions

  1. Ecological Efficiency (1)
  2. Phosphorus Cycle (1)
  3. Species Diversity (1)
  4. Ecosystem (1)
  5. Limiting Factor (1)
  1. a A factor that controls a process such as an organisms growth or species population, size or distribution (ex. sunlight in a rainforest).
  2. b 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. c The movement of phosphorous through the lithosphere, hydrosphere, and biosphere (sig. Scientists analyze the amounts of phosphorus amounts throughout the earth and discover its essentiality for plants and animals in the form of ions).
  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 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 Multiple choice questions

  1. 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).
  2. Climatically and geographically defined as similar climatic conditions on earth and often referred to as "ecosystems" (ex. Tundra, tropical rain forest, and Taiga).
  3. A group of interacting species sharing a populated environment (ex. human communities, plant communities, and animal communities)
  4. 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. The production of organic compounds from atmospheric or aquatic carbon dioxide, principally through the idea of photosynthesis (ex. reduced carbohydrate: CO2 + H2O + light CH2O + O2).

5 True/False questions

  1. Ecotone (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).

          

  2. Hydrosphere (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).

          

  3. Law of Tolerance (2)The range of conditions in which an organism can survive and thrive (sig. can mathematically predict the amount of a population with given standards in an ecosystem).

          

  4. Leaching (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. 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).
