In one sentence, 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, C6H12O6 + 6O2 -> 6CO2 + 6H2O + ATP, shows that plants cycle matter because the glucose (C6H12O6) taken in by plants from the environment is broken down into carbon dioxide (6CO2) and water (6H2O) during respiration, releasing energy in the form of ATP, and then the carbon and oxygen atoms from the carbon dioxide are used by the plant to create new glucose molecules through photosynthesis, completing the cycle.
In plant cellular respiration, glucose (C6H12O6) is broken down into carbon dioxide (6CO2) and water (6H2O), releasing energy, and the carbon and oxygen atoms are then reused in photosynthesis to create new glucose molecules, completing the cycle of matter.
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 in one sentence, citing evidence relating to energy flow and how plants support ecosystems.(4 points) make it short
Energy is lost as it moves up the food chain, with only about 10% being transferred from one trophic level to the next, leading to less biomass at higher trophic levels. Plants, as primary producers, support ecosystems by converting solar energy into organic compounds through photosynthesis, making them the most abundant and providing the base of the food pyramid.
Ocean ecosystems are sensitive to the chemical composition of the water. Any excess compounds can upset the balance and cause damage to organisms. In three sentences, describe how reducing consumption of fossil fuels can help the ocean ecosystem. (4 points)
make the three sentences very short
Reducing consumption of fossil fuels can decrease carbon dioxide emissions, lowering ocean acidification and reducing the harm to marine life. By using alternative energy sources, less pollution is released into the atmosphere, resulting in cleaner air and water for ocean ecosystems. Protecting ocean health by reducing fossil fuel use is vital to preserving the delicate balance of marine ecosystems.
Reducing fossil fuel consumption decreases carbon dioxide emissions, alleviating ocean acidification and protecting marine life.
