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.

• 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.

• 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.

• Leaching: extraction of certain materials from a carrier into a liquid

• Trophic Efficency: the transfer of energy up trophic levels .
