Energy flows…(and is lost)

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.

Ecology. What is Ecology? Ecology is the study of interactions among organisms (biotic factors) and between organisms and their environment (abiotic factors).

Nutrition and Energy Flow What eats what?. How organisms get energy Autotrophs make their own nutrients Autotrophs make their own nutrients Plants use.

Energy Flow in an Ecosystem. Autotrophs: organisms that manufacture their own nutrients using stored energy or energy from the sun –Examples? Heterotrophs:

 the transfer of energy and matter in the form of food when one organism eats another organism.

Energy Flow in an Ecosystem. Energy flows through an ecosystem as one organism eats another. The way in which energy flows can determine how many species.

Energy Transfer Cards (Monday Review) A dead plant and animal leaves behind nutrients and energy in the organic material that made up its body. Scavengers can feed on the carcass but unused energy and nutrients are still left behind. Biomass – bones, feathers, fur, insect exoskeletons, wood, leaves, feces Decomposers release the remaining carbon dioxide and nutrients such as nitrogen and phosphorus Decomposers: Fungus, bacteria, worms, and insects.

Energy Pyramids http://www.brainpop.com/ science/energy/energypyramid/

10% Rule – Energy Pyramid An energy pyramid shows the flow of energy in a community. Each level represents different groups of organisms that could make up a food chain. The bottom level indicates producers, and the other levels are consumers. At each level, about 90% of the energy is used by the organism. Only 10% is available to be passed on to the organism that eats it (the next trophic level)
