Characteristics of Living Things

KEY POINTS: 1. Energy enters an ecosystem in the form of sunlight and flows through the system to each cell and organism 2. Matter interacts, changes, and recycles through an ecosystem 3. Populations of organisms survive by maintaining interdependent relationships with each other and by using

available biotic and abiotic resources from the environment 4. Species depend upon one another and the environment for survival 5. Energy is transferred through interdependent systems to support life
