  • How is carbon returned to the environment?
    When producers and consumers break down the food to obtain energy, they release carbon dioxide to the environment.
  • Who takes in carbon in the carbon cycle?
    Most producers take in carbon dioxide gas from the air during photosynthesis.
  • What is nitrogen used for?
    building protein in animals
  • What is Evaporation?
    Evaporation is the process by which molecules at the surface of liquid water absorb enough energy to change to a gas.
  • How do consumers get carbon compounds in the carbon cycle?
    Consumers eat other organisms and take in their carbon compounds.
  • What is Condensation?
    The process of a gas changing to a liquid is condensation.
  • Most organisms _______ use nitrogen gas, therefore nitrogen needs to be ______?
    cannot, fixed
  • What is Precipitation?
    precipitation: rain, snow, sleet, or hail.
  • What does The Law of Conservation of Mass state?
    The Law of Conservation of Mass states that matter is neither created nor destroyed during any chemical or physical change.
  • The nitrogen cycles from ________ to ___________ many times
    producers; consumers
  • Describe the oxygen cycle?
    . Producers release oxygen as a product of photosynthesis. Most organisms take in oxygen from the air or water and use it to carry out cellular respiration
  • How can nitrogen fixation occur in the environment?
    by lightning
  • What does The Law of Conservation of Energy state?
    The Law of Conservation of Energy states that when one form of energy is transformed to another, no energy is lost in the process.
  • What are the three process of the water cycle?
    Evaporation, condensation, Precipitation
  • Who performs nitrogen fixation?
    Certain bacteria that live on the roots of legume plants
  • How do clouds form?
    The water droplets collect around dust particles and eventually form clouds.
  • What has been one of the main cause of an increase in global temperature?
    Burning of fossil fuels
  • How much of the air is nitrogen gas?
    78%
