DE.6. Life Processes
6.1. Structure/Function Relationship
Enduring Understanding: Living systems, from the organismic to the cellular level, demonstrate the complementary nature of structure and function.
6.1.B. The digestive system has major structures that function to break down food for use in the body. The major parts of the digestive system include the mouth, esophagus, stomach, small intestine, and large intestine. (Level: Compact)
8.1. Interactions within the Environment
Enduring Understanding: Organisms and their environments are interconnected. Changes in one part of the system will affect other parts of the system.
8.1.B. All living organisms interact with the living and nonliving parts of their surroundings to meet their needs for survival. These interactions lead to a constant exchange of matter. (Level: Essential)
8.1.D. Changes in an organism's environment may be either beneficial or harmful. Organisms may be affected by other organisms, by various physical factors (e.g., rainfall, temperature), by physical forces (e.g., storms, earthquakes), and by daily, seasonal, and annual cycles. (Level: Essential)
