5 Matching questions

  1. Nitrogen Cycle (1)
  2. Soil (1)
  3. Hydrosphere (1)
  4. Secondary Consumer (1)
  5. Chemosynthesis (3)
  1. a 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. b The biological conversion of one or more carbon molecules and nutrients into organic matter using the "oxidation of inorganic molecules" as a source of energy (ex. producing sulfur: Hydrogen sulfide chemosynthesis': CO2 + O2 + 4H2S → CH2O + 4S + 3H2O).
  3. c A consumer in which consumes the consumer of the plants or autotrophs (ex. foxes, owls, and snakes).
  4. d 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%).
  5. e A natural body consisting of layers of mineral constitutes of variable thickness, which differ from the parent material in their physical, chemical, and mineralogical characteristics (ex. differs from its parent rock in the lithosphere, hydrosphere, atmosphere, and biosphere).

5 Multiple choice questions

  1. 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).
  2. 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).
  3. 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. 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. 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 True/False questions

  1. Gross Primary Productivity (GPP) (3)A consumer in which they get their energy from the consumption of plants (ex. cows, moose, and rabbits).


  2. Humus (1)Any organic matter which has reached a point of stability where it will not break down any further and remain as it is for centuries (ex. mature compost and natural compost used to amend soil).


  3. Biomass (1)Climatically and geographically defined as similar climatic conditions on earth and often referred to as "ecosystems" (ex. Tundra, tropical rain forest, and Taiga).


  4. Anaerobic Respiration (2)The release of energy from glucose or another organic substrate in the presence of Oxygen (ex. takes place in most living things: to get rid of Carbon Dioxide and excess water this is excretion and maximum energy is released from glucose).


  5. Primary Consumer (1)A consumer in which they get their energy from the consumption of plants (ex. cows, moose, and rabbits).
