Food Chains
TEKS Objective
The student is expected to identify and describe the flow of energy in a food chain and predict how changes in a food chain affect the ecosystem such as removal of frogs from a pond or bees from a field.
Essential Understanding
The student knows that organisms have characteristics that help them survive and can describe patterns, cycles, systems, and relationships within the environments.
Science Background
Energy, Ecosystems and the Atmosphere: BioEd Online (video) - Dr. Nancy Moreno introduces concepts related to ecosystems, energy flow through ecosystems and concepts related to producers and consumers.
