- Matter is constantly cycled between living and non living parts of the environment. Processes like photosynthesis and respiration allow the carbon cycle to regenerate needed substances by recycling earth’s atoms. A diagram of the carbon cycle is shown. Each arrow represents a process in the cycle. Which explanation best describes the process in the cycle. Which explanation best describes the process that occurs at the arrow marked B? A) plants use carbon dioxide from the atmosphere in the process of photosynthesis to produce glucose B) plants release carbon dioxide into the atmosphere in the process of photosynthesis to produce glucose C) plants use carbon dioxide from the atmosphere in the process of cellular respiration to convert glucose to atp energy D) plants release carbon dioxide into the atmosphere in the process of cellular respiration to convert glucose to atp energyDescribe the path of a carbon atom through the carbon cycle. Be sure to include the roles of photosynthesis and respiration in each explanation a) Describe your journey starting as a CO2 molecule in the bottom layer dissolved in the water. Describe at least 3 transformations and the organisms involved. b) Describe the journey starting as a molecule of CO2 in the "atmosphere" of the top layer of the bottle. Describe at least three transformations and the organisms involved. c) How could your eco-columnbe used to model the greenhouse effect?Why do we need green plants and other living things that carry out photosynthesis?

- Why do we need to understand photosynthesis?If the sun randomly went dark today, what part(s) of photosynthesis would be directly affected? Group of answer choices a)ETC 1 & 2 b)Krebs cycle c)Calvin cycle d)P680 e)P680 & P700The process of photosynthesis can be modeled in various ways. For example, a chemical equation is one way to represent photosynthesis. 6CO, + 6H,0 ++ +→ 60, + C,H,,O,
- When discussing why the rate of photosynthesis did not increase at higher light intensities, the investigator mentioned the possibility that high light intensities could damage chlorophyll, which would result in a decrease in oxygen production. Which of the following accurately explains the role of chlorophyll in oxygen production during photosynthesis and why damage to chlorophyll would results in lower oxygen production? Select one or more: a. Chlorophyll participates in carbon fixation during the Calvin Cycle. During this process, oxygen molecules are formed. b. Chlorophyll captures energy from sunlight and releases high energy electrons that enter the electron transport chain in the Calvin Cycle. During this process, oxygen molecules are formed. c. Chlorophyll participates in carbon fixation during the light reactions. During this process, oxygen molecules are formed. d. Chlorophyll captures energy from sunlight and releases high energy electrons that enter the electron…Why does the coupling of photosynthesis and respirationresult in the cycling of carbon?What relevance does photosynthesis have to the food chain of life on Earth?
