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."

What is the difference between food chains and food webs? A. Food webs show a single path of energy in an ecosystem, and food chains show all the overlapping food chains in that ecosystem. B. Food chains show a single path of energy in an ecosystem, and food webs show all the overlapping food chains in that ecosystem. C. Food webs show the path of energy in an ecosystem, and food chains show the path of nutrients in that ecosystem. D.
