The chemical equation for cellular respiration, \( \text{C}6\text{H}{12}\text{O}_6 + 6 \text{O}_2 \rightarrow 6 \text{CO}_2 + 6 \text{H}_2\text{O} \), shows that one glucose molecule and six oxygen molecules are converted into six carbon dioxide molecules and six water molecules, cycling carbon, hydrogen, and oxygen. This process demonstrates how plants use carbon from the atmosphere and water from the soil to create glucose, which is then consumed by organisms, returning carbon and oxygen back to the environment.

The chemical equation for cellular respiration, \( \text{C}6\text{H}{12}\text{O}_6 + 6 \text{O}_2 \rightarrow 6 \text{CO}_2 + 6 \text{H}_2\text{O} \), shows that plants take one sugar molecule and six oxygen molecules and change them into six carbon dioxide molecules and six water molecules. This shows how plants use the air and water to make food, and then living things release that air back into the environment.
I apologize for that! Here’s a simpler response:
The equation for cellular respiration shows that plants use one sugar and six oxygen molecules to produce six carbon dioxide and six water molecules. This shows how plants take in air and water to make food, and then living things release the air back into the environment.
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)
In a food pyramid, there is less biomass at the top because energy decreases at each trophic level. Producers, like plants, capture energy from the sun through photosynthesis, and they form the base of the pyramid. As energy moves up to primary consumers (herbivores) and then to secondary and tertiary consumers (carnivores), only about 10% of the energy from one level is transferred to the next due to energy loss through metabolic processes and heat. This energy loss means there are fewer individuals that can be supported at higher levels, leading to very few tertiary consumers compared to the numerous producers at the base. Thus, plants are crucial in supporting ecosystems by providing energy and biomass for all other levels.
Sorry about that! Here’s a simpler explanation:
In a food pyramid, there are fewer animals at the top because energy gets used up as it moves up from plants to animals. Plants, or producers, use sunlight to make their own food and are the most numerous. When animals eat plants, only a small amount of energy passes on to the next level, so there can’t be as many animals higher up. This is why there are a lot of producers and only a few top predators. Plants are important because they give energy to all the other living things in the ecosystem.
