### *Cellular Respiration*
Both plants and animals need to break down food molecules at the cellular level in order to obtain energy. This process is called cellular respiration. This process is dependent on photosynthesis and, since plants perform both processes, we call them autotrophs. Animals are heterotrophs as they need to consume their food from different sources. Use the chemical equations below to answer the questions once you have discussed each other's individual data. You may also want to revisit the data from the activity you did previously called "A Plant's Raw Materials."

Step 1: Describe the relationship between photosynthesis and cellular respiration from the diagram above.
The diagram provided shows that photosynthesis and cellular respiration are interconnected processes. Photosynthesis occurs in the chloroplasts of plant cells, using carbon dioxide (CO2) and sunlight to produce glucose (C^6H^12O6) and oxygen (O2). This process can be represented chemically as: \text{6CO}_2 + \text{6H}_2\text{O} \xrightarrow[\text{Chloroplasts}]{h\nu} \text{C}_6\text{H}_{12}\text{O}_6 + \text{6O}_2 The glucose produced in photosynthesis is used by plants and animals as a source of energy. During cellular respiration, which takes place in the mitochondria, glucose and oxygen are converted back into water and carbon dioxide, releasing energy in the form of ATP (adenosine triphosphate). The chemical equation for cellular respiration is: \text{C}_6\text{H}_{12}\text{O}_6 + \text{6O}_2 \xrightarrow[\text{Mitochondria}]{} \text{6CO}_2 + \text{6H}_2\text{O} + \text{energy (ATP)} So, photosynthesis and cellular respiration are complementary processes that work together to convert light energy into a form that organisms can use, and to recycle the byproducts of these processes.
Step 2: Describe how photosynthesis and cellular respiration power ecosystems of all kinds on this planet.
Photosynthesis and cellular respiration are fundamental processes that drive the flow of energy and matter through ecosystems. Photosynthesis is the primary process that converts sunlight into chemical energy, which is then transferred through the food web via consumption and decomposition. This energy supports the growth, reproduction, and maintenance of all living organisms in an ecosystem. Cellular respiration, on the other hand, is the process that releases the energy stored in organic molecules, allowing organisms to perform various functions, such as growth, movement, and reproduction. The oxygen produced during photosynthesis is used in cellular respiration, creating a closed cycle that links the two processes together. In summary, photosynthesis and cellular respiration are interconnected processes that power ecosystems by converting light energy into chemical energy and recycling the byproducts of these processes.
Final Answer
Animals release carbon dioxide (CO2) and plants absorb carbon dioxide (CO2).
