Question

to usable energy for cells
→ releases some energy as heat to the atmosphere
photosynthesis stores energy, while cellular respiration
releases energy. the products of photosynthesis are the reactants of
cellular respiration. the products of cellular respiration are the ______ of
photosynthesis.
photosynthesis and cellular respiration work together to move ______ and
______ through ecosystems, allowing life to be sustained over time.

Explanation:

1. For the first blank in the photosynthesis - cellular respiration energy relationship: Photosynthesis is a process that captures light energy (from the sun) and converts it into chemical energy (stored in glucose). So it "stores" energy. Cellular respiration breaks down glucose to release energy for the cell's use, so it "releases" energy.
2. For the products - reactants relationship: The products of photosynthesis are glucose and oxygen. The reactants of cellular respiration are glucose and oxygen. Conversely, the products of cellular respiration (carbon dioxide and water) are the reactants of photosynthesis. So the products of photosynthesis are the "reactants" of cellular respiration, and the products of cellular respiration are the "reactants" of photosynthesis.
3. For the last part about what they move: Photosynthesis and cellular respiration work together to move "energy" (photosynthesis stores it, respiration releases it) and "matter" (in the form of carbon, oxygen, hydrogen atoms moving between CO₂, H₂O, and glucose) through ecosystems.

Answer:

• Photosynthesis \(\boldsymbol{\text{stores}}\) energy, while cellular respiration \(\boldsymbol{\text{releases}}\) energy.
• The products of photosynthesis are the \(\boldsymbol{\text{reactants}}\) of cellular respiration. The products of cellular respiration are the \(\boldsymbol{\text{reactants}}\) of photosynthesis.
• Photosynthesis and cellular respiration work together to move \(\boldsymbol{\text{energy}}\) and \(\boldsymbol{\text{matter}}\) through ecosystems, allowing life to be sustained over time.
