- Q: Explain how life, which is so organized could have formed when the universe is said to be headed towards more disorder according to thermodynamics. Use what you have learned about thermodynamics to explain this paradox.arrow_forwardMAKE CONNECTIONS Explain how nitrogen andphosphorus, the nutrients that most often limit primaryproduction, are necessary for the Calvin cycle to functionin photosynthesis (see Concept 10.3).arrow_forwardMAKE CONNECTIONS As noted in Figure 52.15, theaddition of nutrients to a lake can cause an algal bloom.When these algae die, complex molecules in their bodiesare broken down by decomposers using aerobic respiration. Explain why this would reduce the lake’s oxygenlevels (see Concept 9.1)arrow_forward

- Q) Start with a photon of sunlight and a carbon atom in a molecule of carbon dioxide in the atmosphere: model/diagram their pathway from that starting point to their final destination as a glucose molecule that is used for energy in a cell in the plant root. Following your diagram/model, provide a written explanation for what your diagram/model depicts. Make sure both your model and explanation are clear, concise, and have the appropriate level of detail to clearly demonstrate you understand photosynthesis, cellular respiration, and the movement of mass and energy in plants.arrow_forwardQ1: How is a decomposer different from a more typical consumer?
