Flow of Matter and Energy in Ecosystems

The Flow of Matter and Energy in Ecosystems Interactive E-book* explores the systemic interplay and flow of matter and energy throughout ecosystems, populations, and organisms. Webs and pyramids are used to model and communicate about the transfer of energy and cycling of matter within an ecosystem, representing how the total living biomass stays roughly constant—cycling materials from old to new life—accompanied by an irreversible flow of energy from captured sunlight into dissipated heat.

*Interactive E-books are highly interactive, self-directed learning experiences designed to augment understanding of science content and pedagogy. These e-books include high-resolution images, animations, videos, interactive simulations, and embedded assessment.
