3rd Grade Update Science Food Ch ains and Webs Enduring Understandings: • • • Essential Questions: An organism’s habitat provides what is necessary for its survival. Organisms have different roles within an ecosystem. Energy is transferred to support life. • • • What are some interactions between plants and animals? How is energy transferred within ecosystems? How do you differentiate between living organisms and nonliving things? VOCABULARY • • • • • living nonliving organism predator decomposer • • • • • • • • • • • • • • • • • habitat food chain food web scien#fic energy producer algae herbivore • • • daphnia diversity guppies carnivore prey Resultant Knowledge: Resultant Skills: Students will know: Students will be able to: Living, nonliving, and dead objects are found in our environment. Sunlight is the primary source of energy plants use to produce their own food. • • • All food chains begin with the sun. Energy is transferred from one organism to another within a food chain. • All animals depend on green plants for energy. Organisms are classified as producers, consumers, or decomposers depending on their role in the ecosystem. • Classify populations of organisms as producers, consumers, or decomposers by the role they serve in the ecosystem. Sequence the flow of energy through a food chain beginning with the sun. Predict the possible effect of removing an organism from a food chain. Differentiate between the three types of consumers (herbivore, carnivore, omnivore). Categorize organisms as predator or prey in a given ecosystem. There are several effects of removing an organism from a food chain.
