how energy flows through a system


Mitochondria in eukaryotes, animals

Chloroplasts in prokaryotes, plants

Make Energy (ATP)

Plants make energy from the sun

Animals make energy from plants

The energy ATP

Use for cell work

DNA uses ATP for replication and transcription

DNA is used as instructions to make proteins

Proteins are chains of aminoacids

Proteins are part of the food chain

Food chains have trophic cycles:
  • levels go up from producers to consumers

Organisms live in communities in ecosystems

The Planet Earth has a series of cycles

Energy moves through the cycles



systems of energy flow



Photosynthesis in Chloroplasts

ATP generation in Mitochondria/ Krebs Cycle

Aerobic vs Anaerobic Respiration

Food Chain: Cycle of Matter and Population Growth

Geoscience: Global Energy Transfer Systems:
  • Carbon Cycle, water cycle

Cycle of matter and population growth:

Energy from sun moves through system by turning into food in the trophic cycle, higher number in trophic cycle, more of a consumer

Book pages 437 and 438

Energy transfer systems to consider:

How photosynthesis transforms light energy into stored chemical energy.

How carbon, hydrogen, and oxygen from sugar molecules may combine with other elements  to form amino acids and/or other large carbon-based molecules. 

LS1.C: Organization for Matter and Energy Flow in Organisms
  • The sugar molecules thus formed contain carbon, hydrogen, and oxygen: their hydrocarbon backbones are used to make amino acids and other carbon-based molecules that can be assembled into larger molecules (such as proteins or DNA), used for example to form new cells.
  • As matter and energy flow through different organizational levels of living systems, chemical elements are recombined in different ways to form different products.

Cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed, resulting in a net transfer of energy.

Energy and Matter
  • Energy cannot be created or destroyed—it only moves between one place and another place, between objects and/or fields, or between systems.

Construct and revise an explanation based on evidence for the cycling of matter and flow of energy in aerobic and anaerobic conditions.

Cycles of Matter and Energy Transfer in Ecosystems
  • Photosynthesis and cellular respiration (including anaerobic processes) provide most of the energy for life processes.
  • Hydrothemrmal vents with anaerobic bacteria


Use mathematical representations to support claims for the cycling of matter and flow of energy among organisms in an ecosystem.

Develop a model to illustrate the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.

Cycles of Matter and Energy Transfer in Ecosystems
  • Photosynthesis and cellular respiration are important components of the carbon cycle, in which carbon is exchanged among the biosphere, atmosphere, oceans, and geosphere through chemical, physical, geological, and biological processes.

Energy in Chemical Processes
  • The main way that solar energy is captured and stored on Earth is through the complex chemical process known as photosynthesis.
