In one or two sentences, explain how the chemical equation for cellular respiration shows that plants cycle matter. Include the numbers of molecules and atoms involved to support your explanation.(2 points)
The chemical equation for cellular respiration shows that plants cycle matter by taking in six molecules of carbon dioxide (CO2) and six molecules of water (H2O), then releasing six molecules of oxygen (O2) and producing one molecule of glucose (C6H12O6) and six molecules of water. This demonstrates the cycling of carbon and oxygen atoms through photosynthesis and cellular respiration.
In a food pyramid, there is typically less biomass at the top (i.e., there are very few individual tertiary consumers, whereas there are numerous individual producers). In three to five sentences, explain this phenomenon, citing evidence relating to energy flow and how plants support ecosystems.(4 points)
