- a 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).
- b Organisms that break down dead or decaying organisms that carry out of the process of decomposition (ex. fungi and worms).
- c A group of interacting species sharing a populated environment (ex. human communities, plant communities, and animal communities)
- d Any product of condensation of atmospheric water vapor that falls under gravity (ex. rain, snow, sleet, hail, and graupel).
- e The rigid outtermost shell of a rocky planet (ex. Earth consists of a crust and uppermost mantle within it's lithosphere.
5 Multiple Choice Questions
- 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).
- A factor that controls a process such as an organisms growth or species population, size or distribution (ex. sunlight in a rainforest).
- A renewable energy source in which a biological material is from living or recently deceased organisms (ex. garbage, wood, waste, landfill gasses, and alcohol fuels).
- 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).
- The measure of the void spaces within material, and is a fraction of the volume of voids over the total volume (sig. The porosity of a rock, is an important consideration when attempting to evaluate the potential volume of water or hydrocarbons it may contain).
5 True/False Questions
Soil (1) → 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).
Trophic Levels (1) → An organism and the position it occupies on the food chain (ex. primary producers level 1 and predators at level 3).
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).
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).
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).
