Life Science: Matter, energy, and organization in living systems Grades 9-12, page 186 As matter and energy flows through different levels of organization
of living systems--cells, organs, organisms, communities--and between living
systems and the physical environment, chemical elements are recombined
in different ways. Each recombination results in storage and dissipation
of energy into the environment as heat. Matter and energy are conserved
in each change.

Benchmark 5E The Living Environment:
Flow of Matter and Energy
Grades 9-12, page 121
The chemical elements that make up the molecules of living things pass
through food webs and are combined and recombined in different ways. At
each link in a food web, some energy is stored in newly made structures
but much is dissipated into the environment as heat. Continual input of
energy from sunlight keeps the process going.
