Matter and energy move freely between and among living things and the physical environment in which they live. Life ultimately depends on the suns energy that is transformed by plants into energy-bearing food through the process of photosynthesis. Energy flows among living things through the food web and is used by all living things for energy, growth, and repair. Molecules of the substances found in living things are continually recycled between organisms themselves and the natural world. In the earth system, the total amount of matter and energy remains constant, even though their forms, availability, and where they are found in any moment are continually changing.Conceptual StrandMatter and energy flow through the biosphere.Guiding QuestionWhat scientific information explains how matter and energy flow through the biosphere?
