Only 10% of the energy at one trophic level is transferred to the next trophic level. Only 10% of an organism's energy is used for growth and reproduction. Only 10% of an organism's energy is used for growth and reproduction. Only 10% of an ecosystem's energy is lost as heat. Only 10% of an ecosystem's energy is lost as heat. Only 10% of the energy in an ecosystem is stored in the form of biomass. Only 10% of the energy in an ecosystem is stored in the form of biomass. Question 15 Which of the following is the correct sequence of stages in cellular respiration?(1 point) Responses Glycolysis, Krebs cycle, Electron transport chain Glycolysis, Krebs cycle, Electron transport chain Glycolysis, Electron transport chain, Krebs cycle Glycolysis, Electron transport chain, Krebs cycle Krebs cycle, Glycolysis, Electron transport chain Krebs cycle, Glycolysis, Electron transport chain Electron transport chain, Glycolysis, Krebs cycle Electron transport chain, Glycolysis, Krebs cycle Question 16 How is carbon recycled through the processes of photosynthesis and cellular respiration?(1 point) Responses Plants convert carbon dioxide into glucose during photosynthesis, and animals release carbon dioxide back into the atmosphere during cellular respiration. Plants convert carbon dioxide into glucose during photosynthesis, and animals release carbon dioxide back into the atmosphere during cellular respiration. Animals convert carbon dioxide into glucose during cellular respiration, and plants release carbon dioxide back into the atmosphere during photosynthesis. Animals convert carbon dioxide into glucose during cellular respiration, and plants release carbon dioxide back into the atmosphere during photosynthesis. Plants take in carbon dioxide and release oxygen, while animals take in oxygen and release carbon dioxide. Plants take in carbon dioxide and release oxygen, while animals take in oxygen and release carbon dioxide. Both plants and animals convert carbon dioxide into oxygen, which is then used by other organisms. Both plants and animals convert carbon dioxide into oxygen, which is then used by other organisms.
