- In habitats where water conservation is not especially necessary, is CAM metabolism more or less advantageous than C3 or C4 metabolism? Why?arrow_forwardWhy is carbon important to life? What is the role of photosynthesis in the carbon cycle? What is the role of cellular respiration in the carbon cycle? How does the burning of fossil fuels contribute to the carbon cycle? How do death and decomposition contribute to the carbon cycle? Why is nitrogen important to life? How much of the atmosphere is made up of nitrogen gas? Why is N2 (atmospheric nitrogen) not usable by most organisms? What organisms are responsible for nitrogen fixation? How do plants receive the nitrogen that they require? Why are bacteria essential to the carbon and nitrogen cycles?qarrow_forwardplz explain in details. Organisms must do tasks in order to survive. This work requires either light for photosynthesis or the chemical potential energy of organic molecules as an energy input. Explain the necessity for energy in living organisms and provide two (2) examples. Explain the oxidative phosphorylation process, particularly the involvement of oxygen. Discuss the generation of a low yield of ATP from anaerobic respiration and the formation of lactate in mammals.arrow_forward
