Ecology Glossary Terms Unit 1

  1. Ecosystem
    all the interacting parts of a biological community and its environment
  2. Sustainable Ecosystem
    an ecosystem that is capable of withstanding pressure and giving support to a variety of organisms
  3. Biotic
    the living parts of an ecosystem
  4. Abiotic
    the non-living parts of an ecosystem
  5. Lithosphere
    the hard part of Earth's surface
  6. Hydrosphere
    all water found on Earth
  7. Atmosphere
    layer of gases above Earth's surface
  8. Biosphere
    regions of Earth where living organisms exist
  9. Nutrients
    a chemical essential to living things
  10. Eutrophication
    process where nutrient layers in aquatic systems increase, leading to an increase in primary producers
  11. Photosynthesis
    a process that changes solar energy into chemical energy
  12. Trophic Level
    a category of organisms that is defined by how the organisms gain their energy
  13. Biomass
    the total mass of living organisms in a defined area
  14. Trophic Efficiency
    a measure of the amount of energy or biomass transferred from 1 trophic level, to the next
  15. Bioaccumulation
    a process in which an organism ingests materials, especially toxins, faster than it eliminates them
  16. Biomagnification
    a process where the concentration of ingested toxins increases as it moves through trophic levels
  17. Cellular Respiration
    a process that releases energy from organic molecules in the presence of oxygen
  18. Fermentation
    a process that releases energy from organic molecules in the absence of oxygen
  19. Greenhouse Gases
    an atmospheric gas that prevents heat from leaving the atmosphere
  20. Greenhouse Effect
    the warming of the Earth, due to greenhouse gases
  21. Acid Precipitation
