RI.LS2. Life Science: Matter cycles and energy flows through an ecosystem.
LS2 (5-8) SAE-6. Given a scenario trace the flow of energy through an ecosystem, beginning with the sun, through organisms in the food web, and into the environment (includes photosynthesis and respiration).
LS2 (7-8)-6. Students demonstrate an understanding of energy flow in an ecosystem by...
6a. Explaining the transfer of the sun's energy through living systems and its effect upon them.
6d. Creating or interpreting a model that traces the flow of energy in a food web.
LS2 (5-8) SAE-7. Given an ecosystem, trace how matter cycles among and between organisms and the physical environment (includes water, oxygen, food web, decomposition, recycling but not carbon cycle or nitrogen cycle).
LS2 (7-8)-7. Students demonstrate an understanding of recycling in an ecosystem by...
7a. Diagramming or sequencing a series of steps showing how matter cycles among and between organisms and the physical environment.
7b. Developing a model for a food web of local aquatic and local terrestrial environments.
7c. Explaining the inverse nature or complementary aspects of photosynthesis/respiration in relation to carbon dioxide, water and oxygen exchange.
7d. Conducting a controlled investigation that shows that the total amount of matter remains constant, even though its form and location change as matter is transferred among and between organisms and the physical environment (e.g., bottle biology, mass of a closed system over time).
