  1. Ecosystem
    The interactions that occur between various organisms within a biological community and that community's environment.
  2. Sustainable Ecosystems
    An ecosystem that is capable of withstanding various internal of external pressures and giving support to a variety of organisms and allowing them to live and thrive at the optimum capacity.
  3. Biotic
    Anything in an ecosystem that's living or was living. E.g cows, trees, a dead deer.
  4. Abiotic
    Anything in an ecosystem that's not living. E.g rocks, mountains, a prehistoric fossil.
  5. Symbiosis
    • How members from two or more different species in close proximity interact with each other.
  6. Mutualism
    When both members of different species benefit equally.
  7. Parasitism
    When one member on an interaction between two different species benefits while the other one is harmed.
  8. Predation
    One organism consumes another for energy and sustenance.
  9. Comeptition
    When two or more organisms are forced to compete for the same resources due to a shortage of resources.
  10. Eutrophication
    Is the process on adding Nitrogen and Phosphorous to an ecosystem that pushes it beyond the normal nutrient cycle and beyond sustainability.
  11. Photosynthesis
    A series of reactions occurring in the Thylakiods of a plant cell's chloroplast that turn sunlight energy, 6 molecules of carbon dioxide, and 6 molecules of water into 1 molecule of glucose and 6 molecules of oxygen. to be later turned into starch which then the plant uses as food.
  12. Trophic levels
    Categories of organisms that are defined by how hey gain energy in relation to other organisms. This is usually represented as a food pyramid or as a food chain. These categories are Primary producers (plants, Primary consumers (animals that eat the plants E.g grasshoppers), secondary consumers (frogs), and Tertiary consumers (hawks).

  13. Primary producers
    Can make their own food. E.g photosynthetic plants and bacteria.
  14. Consumers
    Any organism that cannot create their own food and thus consume other organisms for energy.
  15. Biomass
    The total mass of living organisms in a defined group or area.
  16. Trophic Efficiency
    A measure of how energy or biomass is transferred from one trophic level to another (mainly through predation).

  17. Bioaccumulation
    When minerals (mainly toxins) enter an organism's body at a rate faster than their body can expel it.
  18. Biomagnification
    The census in concentration of toxins as they are transported from one trophic level to another through predation.
  19. Lithosphere
    The hard layer around earth. Includes rocks and minerals.
  20. Hydrosphere
    The liquid part of earth's surface. Includes oceans, lakes, rivers, creek (any body of water).
  21. Atmosphere
    The gases that surround earth's Lithosphere and Hydrosphere. Includes air.
  22. Biosphere
    All living creatures on earth living in all spheres. Includes all living or formerly living creatures in all ecosystems.

  23. Nutrients
    Nutrients are chemicals that all Biotic creatures require to live and survive. Calcium, and glucose are just some of the many nutrients that Biotic life requires to survive.
  24. Acid precipitation
    • Rain, snow, or sleet that is infected with acidic chemicals ( Sulfuric acids and Nitric acids) from excessive release of chemicals in the atmosphere. 
  25. Cellular Respiration
    • A series of reactions (Glycosis, Krebs cycle, and electron transport chain) to turn glucose into a usable form of energy (ATP) under aerobic conditions. It requires 1 molecule of glucose, 6 molecules of oxygen and expels 6 molecules of carbon dioxide, 6 molecules of water, and energy.
  26. Fermentation
    A process that releases chemicals from organic molecules under anaerobic conditions.

  27. Greenhouse gases
    Gases in the atmosphere that prevent heat from leaving earth's Exosphere, which in turn increases earth's temperature. Some of these chemicals are water vapor and carbon dioxide.

  28. Greenhouse effect
    The increase in earth's temperature as a result of greenhouse gasses trapping in heat that would under normal circumstances leave earth.
