5 Matching questions

  1. Percolation (3)
  2. Decomposer (1)
  3. Aquatic Life Zone (1)
  4. Law of Tolerance (2)
  5. Habitat (1)
  1. a Zones under the water where aquatic life is present which can be characterized by aquatic ecosystems (ex. marine ecosystem and freshwater ecosystem).
  2. b The movement and filtering of fluids through porous materials (ex. coffee percolation, the solvent being water, permeable substances being coffee grounds, and soluble constitutes are the objects that give coffee taste and color).
  3. c 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).
  4. d Organisms that break down dead or decaying organisms that carry out of the process of decomposition (ex. fungi and worms).
  5. e An ecological or environmental inhabited by a particular species of organism (ex. African elephant habitats spread throughout Africa and Microhabitats)

5 Multiple choice questions

  1. A consumer in which they get their energy from the consumption of plants (ex. cows, moose, and rabbits).
  2. A carnivorous feeding behavior in which a predator consumes a corpse that was not killed to be eaten by the predator (ex. vultures, blowflies, and raccoons).
  3. Relating to, produced by, or caused by living organisms (ex. wood, linoleum, straw, humus and crude oil).
  4. A soil property used to describe the relative proportion of different grain sizes of mineral particles in the soil (ex. clay, silt, sand, and loam).
  5. 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).

5 True/False questions

  1. Range of Tolerance (1)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).

          

  2. 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).

          

  3. 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).

          

  4. 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).

          

  5. Nitrogen Fixation (2)The natural process by which nitrogen in the universe is converted to ammonia (ex. used by many prokaryotes including bacteria and actinobacteria).
