• Decomposer is a final consumer
• Types of Ecosystems

  • Macroecosystems
  • Microecosystems
• Types of consumers

  • Herbivores
  • Carnivores
  • Omnivores
• Distance is a scalar quantity representing the total distance traveled
• Motion is associated with a change in the location or position of an object
• Thermal equilibrium


  The bodies in contact reach equal temperature
• Acceleration


  A vector quantity representing the rate at which an object changes its velocity
• Parasitism is a relationship where one organism benefits and the other is harmed
• Vector


  A quantity that has both magnitude and direction (e.g., velocity, weight, friction)
• Hydrophytes are plants that live in water
• Physical contact between bodies does not allow the transfer of heat
• Commensalism is a relationship where one organism benefits and the other is not harmed
• Duration refers to the length of day and night as seasons change
• Amensalism is a relationship where one organism is inhibited or killed while the other is unaffected
• Mutualism is a relationship where both participating organisms benefit
• Displacement


  A vector quantity representing the shortest distance between initial and final position
• is a relationship where one organism is inhibited or killed while the other is unaffected
• Scalar quantity


  A quantity that has magnitude only (e.g., speed, mass, volume, time)
• Heat continues to flow until the bodies reach thermal equilibrium
• Light intensity is the amount of light that strikes the earth's surface
• The relationship where one organism benefits and the other is harmed is called predation
• Speed is a scalar quantity representing how fast a body is traveling
• Light intensity


  Amount of light that strikes the earth's surface
• Duration


  Length of day and night as seasons change
• Primary source of energy in earth is light
• Vector is the speed in a given direction
• What are the 3 types of heat transfer?

  • Conduction

  • Convection

  • Radiation
• Neutron has zero charge 
• Electron has negative charge
• Proton has positive charge
• Wave is vibration in space in time
• Crest is the highest part of a wave 
• Trough is the lowest part of a wave
• Amplitude is the distance between the origin to crest/trough 
• Wave length describes the length of the wave
• Radio waves is used for communication
• Microwaves is used to cook and heat food
• Infrared is for warm or heat
• Visible light and be detected by our eyes
• Ultraviolet can cause sunburn and may damage our skin and eyes
