The Energy Flow Cycle

• The Energy Flow starts with solar energy from the
  sun captured by plant and turned into glucose
  through the process of photosynthesis by
  producers.
• The producers are then consumed by the first
  level of consumers. This is the start of the
  food chain/web.

• The solar energy passes through the atmosphere,
  lithosphere, hydrosphere and into the biosphere.

• Trophic efficiencies generally range from 5 to
  20 but only 5 to 20 of primary producer
  biomass consumed is converted into new consumer
  biomass.

Cycle Importance

• The energy cycle is important because it provides
  energy for animals and when they die, unused
  energy is recycled.

Key Terms

• Solar radiation radiant energy emitted by a sun
  as a result of its nuclear fusion reactions
• Dispersal the act of scattering
• Migration the act of going from one country,
  region, or place to another
• Erosion the process by which the surface of the
  earth is worn away by the action of water,
  glaciers, winds, waves, etc.

9

• Deposition a natural accumulation or occurrence,
  especially the laying down of matter by a natural
  process.
• Longwave radiation is the energy leaving the
  earth as infrared radiation at low energy
• Heat the state of a body perceived as having or
  generating a relatively high degree of warmth.

10

• Consumers a heterotrophic organism that ingests
  other organisms or organic matter in a food
  chain.
• Decomposers An organism, often a bacterium or
  fungus, that feeds on and breaks down dead plant
  or animal matter, thus making organic nutrients
  available to the ecosystem.

11

• Leaching extraction of certain materials from a
  carrier into a liquid
• Trophic Efficency the transfer of energy up
  trophic levels .
