  1. a cycle that replaces minerals and other nutrients in the environment
    Nutrient cycle
  2. what are the three major processes in the hydrogen cycle
    • evaporation
    • condensation
    • precipitation
  3. within an organism's tolerance range for temperature or for another factor is an ideal range
    optimum range
  4. bacteria and fungi that feed on detritus by secretin enzymes that break it down into simpler molecules
  5. like decomposer except they help to break it down into smaller pieces and speed up the process of decay
  6. model used by ecologist to show the nutritional relationships among organisms in an ecosystem
    food chain
  7. model used by ecologists to show allĀ  possible feeding relationships at each trophic level
    food web
  8. shows energy transferred from one trophic level to the next.
    energy pyramid
  9. represents the total mass of living matter per unit area
    biomass pyramid
  10. represents the number of organisms at each trophic level and shows the population size usually decreases at each higher trophic level
    number pyramid
  11. organisms living in close association with one another in a type of relationship
  12. A type of symbiosis with a relationship in which both organisms benefit
  13. Symbiosis that in a relationship between two organisms in which on (parasite) benefits while the other(host) is harmed
  14. a symbiotic relationship in which one organism benefits and the other is neither harmed nor helped
  15. All the living things in an ecosystem
  16. Biomes Terrestrial biomes that show great variations in temperature, dissolved nutrients, gases, and sunlight penetration
    aquatic biomes
  17. coastal zones, are the regions that extend past the intertidal zone until you reach the edge of the continental shelf
    Neritic zones
  18. organisms that colonize a disturbed ecosystem
    pioneer species
