A single path that shows how each living thing gets it’s food. The flow of energy begins with the SUN and transfers through the chain. Always starts with a plant (producer) and ends with a predator! More energy at the beginning than the end.

 Network of many food chains.  Allows an organism to survive better than a food chain because there are more options for food!

1. PRODUCERS: are Plants! They produce or make their own food through photosynthesis! Always on the bottom of the food chain/web and always have the MOST energy. 2. DECOMPOSERS: Organisms that break down dead plant and animal matter. They are at every level of a food chain/web.  Fungus  Bacteria  Worms  Insects  Flies and Larva 3. CONSUMERS: they “consume” – All animals are consumers. The get their energy from what they feed on. Top of the food chain or food web.  A. Carnivore  Eats meat  B. Herbivore  Eats only plants  C. Omnivore  Eats both meat and plants

 Shows how much energy goes from one level to the next…. “CHEMICAL ENERGY”  Energy decreases as you move to the top of the pyramid.  10% RULE: SAYS only 10% of the chemical energy transfers from one trophic level to the next trophic level.

 It leaves behind ________ and _________ in the organic material that made up its body.  Scavengers can feed on carcass,but they leave behind a LARGE amount of energy and nutrients.  Bones, feathers, and exoskeletons,fur, and wood contain unused energy.  DECOMPOSERS complete the process by changing the leftover organic matter into _________ ________ and ____________.

 Shows an organisms position in a food chain.  Producers have LOTS of energy.  10% RULE: SAYS only 10% of the chemical energy transfers from one trophic level to the next trophic level.

Lots of ENERGY!!! Very little Energy!

How would you draw an energy pyramid using the animals in the following food web? cricketduck Grass small fishlarge fishhawk Algaesnailsnake

 Occurs in all plants at the cellular level!  Releases energy captured and stored within a plant.  Opposite of photosynthesis…does NOT require light! Glucose + Oxygen CO2+ water + energy Respiration allows a plant to process food and grow.

 Total mass of all living matter in a given area.  Biomass is converted into ENERGY!!  This energy is released as HEAT!
