Solved in 3 steps
- If space exploration revealed a planet that had the water, sunlight, and climate, necessary to maintain good plant life, would it be possible to produce oxygen and food necessary to sustain human life?Explain why an increase in oxygen in the atmosphere to 50 percent would be dangerous to living things?Create a diagram that trace the pathway of oxygen from plants to human lungs and give a brief explanation
- use the diagram to explain in detail how energy is transferred through the atmosphereUse the kinetic model of gases to explain why light gases, such as H2 and He, are rare in the Earth's atmosphere but heavier gases, such as O2, CO2, and N2 are abundant.How would an increase in the rate of cellular respiration influence the rate of net photosynthesis? (Answer should be based on the book of Smith & Smith, 'Elements of Ecology')
