Question
Chapter 37, Problem 9RQ
Summary Introduction
To determine: The origin of oxygen on earth.
Introduction: Geography is the study of the surface and atmosphere of the earth. It can be studied with the help of physical features of the earth, composition of the atmosphere, and motions in the atmosphere.
Summary Introduction
To determine: The effect of ceasing photosynthesis on earth’s supply of oxygen.
Introduction: Photosynthesis refers to the process by which bacteria and plants use solar energy to produce carbohydrates from carbon dioxide and water. This carbohydrate gets converted into pyruvic acid, which releases a form of energy by respiration.

- Why are carnivores, such as lions, dependent on photosynthesis to survive?arrow_forwardMatter 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 energyarrow_forwardWhy, then, is there such a diversity of photosynthetic organisms?arrow_forward
- The law of conservation of matter states that no matter on earth can be created or destroyed. Using the following equation: 6H2O + 6CO2 + Sunlight—> C6H12O6 + 6O2, explain how the process of photosynthesis is an example of this.arrow_forwardIn addition to the pigments commonly associated with photosynthesis, a certain photosynthetic species contains two additional pigment types. Which of the following best supports the claim that this species is better adapted to environmental changes than other photosynthetic species are? a) The additional pigments allow the species to outcompete other species for the wavelengths of light commonly used in photosynthesis. b) The increased pigment concentration better facilitates energy production within the cells of the species. c) The pigment combination allows the organism to absorb heat as well as light, making better use of available energy. d) The additional pigments allow the species containing them to harvest energy from wavelengths of light that the other photosynthetic species cannot use.arrow_forwardList three major steps that are hypothesized to have occurred in the evolutionary history of photosynthesis.arrow_forward

- how the relationship between photosynthesis and cellular respiration prove that the Laws of Conservation of Mass and Energy exists in living systems?arrow_forward(a) It can be argued that, if life were to exist elsewhere in the universe, it would require some process like photosynthesis. Why is this argument reasonable? (b) If the starship Enterprise were to land on a distant planet and find no measurable oxygen in the atmosphere, could the crew conclude that photosynthesis is not taking place?arrow_forwardWhy is photosynthesis important for humans and what will happen if it stops?arrow_forward
