- Ecotone (1)
- Consumer (1)
- Biotic Potential (2)
- Chemosynthesis (3)
- Nitrogen Cycle (1)
- a 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).
- b 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)
- c 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%).
- d 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).
- e Any individuals that use goods or services generated within an economy (ex. business consumers and hunting consumers [foxes, wolves, and eagles]).
5 Multiple Choice Questions
- Non-living chemical or physical factors within the environment (ex. radiation, temperature, and water).
- 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).
- 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).
- The global sum of all the ecosystems together, often referred to as the "zone of life of earth" (sig. Thought to evolved from through a process of biogenesis or biopoesis over 3.5 billion ago).
- A group of interacting species sharing a populated environment (ex. human communities, plant communities, and animal communities)
5 True/False Questions
Anaerobic Respiration (2) → A way for an organism to produce usable energy in the form of ATP without the presence of Oxygen (ex. glucose + 3NO3- + 3H2O 6HCO3- + 3NH4+, ΔG0' = -1796 kJ) (http://en.wikipedia.org/wiki/Anaerobic_respiration#Examples_of_anaerobic_respiration).
Limiting Factor (1) → A factor that controls a process such as an organisms growth or species population, size or distribution (ex. sunlight in a rainforest).
Precipitation (1) → All the organisms which belong to the same species and live in the same geographical area (ex. human population, plant population, and animal populations).
Percolation (3) → 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).
Tertiary (higher level) consumers (1) → A carnivore at the topmost of the food chain that feeds on other carnivores (ex. humans).
