Energy FlowPage 65 of INB

Essential Question:

•How does energy flow in an ecosystem?

Energy flow:

•When 1 organism eats another, the energy from the 1 eaten is transferred to the one eating.•Organisms are classified by how they get their energy.

Producers:•Producers: produce (make) their own energy.•They change the energy available in the environment into food.•Photosynthesis or chemosynthesisLight energy + Carbon Dioxide + Water

Sugar + Oxygen

Consumers:

•Can not make their own energy must consume/eat another organism•Classified by what they eat.

Consumers:

•Herbivores: eat only producers/plants•Omnivores: eat both producers and consumers•Carnivores: eat only consumers•Detrivores: eat dead plant and animal material.

Food Chain:

•Food Chain•How energy flows in an ecosystem through feeding relationships.•Energy is lost along each step in the food chain

Food Web:

•Show several interconnecting food chains.•Energy pyramid: Food energy available at each level of a community or trophic level.
