STANDARDS
This WebQuest meets the following Missouri Grade Level Expectations for the third grade in Science and Communication Arts:
Science
Standard 4: Changes in Ecosystems and Interactions of Organisms with Their Environments
2. Matter and energy flow through an ecosystem
Concept A: As energy flows through the ecosystem, all organisms must capture the portion of energy available to them and transform it to a useable form.
Objectives:
a. Identify sunlight as the primary source of energy plants use to produce their own food.
b. Classify populations of organisms as producers, consumers, decomposers by the role they serve in the ecosystem.
c. Differentiate between three types of consumers (herbivore, carnivore, omnivore)
d. Categorize organisms as predator or prey in a given ecosystem.
e. Sequence the flow of energy through a food chain beginning with the sun.
f. Predict the possible effects of removing an organism from a food chain.
