  • What is Transpiration?
    Evaporation of water from leaves of a plant
  • What are Decomposers?
    Organisms that break down the dead remains of other organisms
  • What is a Quaternary consumer?
    An organism that eats tertiary consumers
  • What is a group of ecosystems classified by the climate and plant life?
    Biome
  • What are Consumers?
    Organisms that eat living producers and/or other consumers for food
  • What are the non-living physical and chemical conditions affecting organisms?
    Abiotic factors
  • What are a group of populations living and interacting in the same area?
    Community
  • A close relationship between two or more species where at least one benefits
    Symbiosis
  • The Oxygen Cycle
    The physical processes that cause oxygen to be used up and replenished collectively
  • What is ammonification?
    is a natural process where organic nitrogen compounds transform into ammonia or ammonium. It is part of the decomposition process.
  • Denitrification
    A process that effectively takes nitrogen out of the food chain until nitrogen-fixing bacteria can once again turn it into the more active nitrogen.
  • What is any living part of an environment?
    Biotic factors
  • What is a series of steps in which organisms transfer energy by eating and being eaten?
    Food Chain
  • What is a Tertiary consumer?
    An organism that eats secondary consumers
  • A measure of the total amount of living amount of living tissue of organisms within a trophic level in an ecosystem
    Biomass
  • What is an association of living organisms and their physical environment?
    Ecosystem
  • What has been designed to take nitrogen gas from the air and convert it.
    Nitrogen-fixing bacteria
  • What does a Food Web do?
    It links all the food chains in an ecosystem together
  • What is the study of the interactions between living and nonliving things?
    Ecology
  • What is a species?
    A unit of one or more populations of individuals that can reproduce under normal conditions, produce fertile offspring, and are reproductively isolated from oth
  • The process by which certain gases (principally water vapor, carbon dioxide, and methane) trap heat that would otherwise escape the Earth and raidiate into space
    Greenhouse Effect
  • Primary productivity
    A rate at which producers in an ecosystem build biomass
  • What converts nitrogen gas into chemically active molecules that many organisms can use?
    The Nitrogen Cycle
  • Ecologists use three types of ecological pyramids depending on what information they want to depict. What are they?
    Energy pyramids, Biomass Pyramids, or Pyramids of numbers
  • What is the sum of all earth's ecosystems in land, water, or air
    Biosphere
  • What is a group of interbreeding organisms coexisting together.
  • An organism that eats producers?
    Primary Consumer
  • What is an Ecological pyramid?
    Pyramid-shaped diagrams that show the amount of amount of energy or matter at each trophic level in an ecosystem
  • What is the Carbon Cycle?
    It regulates the amount of amount of carbon in ecosystems, principally by keeping careful track of carbon dioxide.
  • What are Producers?
    Organisms that produce their own food
  • What is a Secondary consumer?
    An organism that eats primary consumers
