5 Written questions

5 Matching questions

  1. Phosphorus Cycle (1)
  2. Ecological Efficiency (1)
  3. Carbon Cycle (1)
  4. Aquatic Life Zone (1)
  5. Population (1)
  1. a 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).
  2. b Zones under the water where aquatic life is present which can be characterized by aquatic ecosystems (ex. marine ecosystem and freshwater ecosystem).
  3. c 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).
  4. d All the organisms which belong to the same species and live in the same geographical area (ex. human population, plant population, and animal populations).
  5. e 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).

5 Multiple choice questions

  1. 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).
  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. 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).
  4. Specific layer in the land area that is parallel to the soil surface that possesses physical characteristics which differ from the layer above and beneath (ex. alluvium, sand dunes, and volcanic ash).
  5. An organism and the position it occupies on the food chain (ex. primary producers level 1 and predators at level 3).

5 True/False questions

  1. Species Diversity (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).

          

  2. Sulfur Cycle (1)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%).

          

  3. Nitrogen Cycle (1)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%).

          

  4. 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).

          

  5. Abiotic(1)Non-living chemical or physical factors within the environment (ex. radiation, temperature, and water).
