A student made lists of structures observed in cells from two different organisms. Which statement describes the most likely difference in the way that organism 1 and organism 2 obtain energy?

• Only organism 1 uses solar energy to make energy-rich compounds.

• Only organism 1 stores solar energy until it is needed for its life processes.

• Only organism 2 produces molecules for long-term energy storage.

• Only organism 2 transforms food energy into ATP during cellular respiration.

A cell in the leaf of a green plant performs both photosynthesis and cellular respiration, often at the same time. Which statement best describes how these processes are related to each other?

• Both processes produce carbon dioxide.

• Both processes require energy directly from the Sun.

• Products of one process are used as some of the reactants for the other process.

• Thermal energy from one process is used as the energy source for the other process.
