Warm Up In your notebook, write down: In your notebook, write down: The different types of foods you ate for dinner the last three nights. The different types of foods you ate for dinner the last three nights. Ex: If you had a pasta dish, what other ingredients came with it? Tomato is the base for the sauce; the type of meat used in the dish; etc. Ex: If you had a pasta dish, what other ingredients came with it? Tomato is the base for the sauce; the type of meat used in the dish; etc. Under each item, write the name of the plant, animal, or other organism that was the source of that food. Some foods have more than one source Under each item, write the name of the plant, animal, or other organism that was the source of that food. Some foods have more than one source Ex: Macaroni (wheat plant) and cheese (cow, goat, etc.) Ex: Macaroni (wheat plant) and cheese (cow, goat, etc.)

Energy Flow in Ecosystems Chapter 10, Section 3

Standards S.6.5.a Students know energy entering ecosystems as sunlight is transferred by producers into chemical energy through photosynthesis and then from organism to organism through food webs. S.6.5.c Students know populations of organisms can be categorized by the functions they serve in an ecosystem.

SWBAT describe how much energy is available at each level of an energy pyramid.

Producer An organism that can make its own food.

Consumer An organism that obtains energy by feeding on other organisms.

Herbivores Consumers that eat only plants.

Carnivores Consumers that eat only animals.

Omnivores Consumers that eat both plants and animals.

Scavenger A carnivore that feeds on the bodies of dead organisms, such as catfish and vultures.

Decomposers Break down wastes and dead organisms and return the raw materials to the ecosystem.

Food Chain A series of events in which one organism eats another and obtains energy.

Food Web Consists of the many overlapping food chains in an ecosystem.

Energy Pyramid Shows the amount of energy that moves from one feeding level to another in a food web.

Energy Roles Each of the organisms in an ecosystem fills the energy role of producer, consumer, or decomposer.

Food chains & Food webs The transfer of energy from organism to organism in an ecosystem can be shown in diagrams called food chains and food webs.

Food chains & Food webs The transfer of energy from organism to organism in an ecosystem can be shown in diagrams called food chains and food webs.

Energy Pyramids The most energy is available at the producer level of the pyramid. As you move up the pyramid, each level has less energy available than the level below.
