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_forwardWhat is the connection between cellular respiration and a global phenomenon like climate change?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_forward
- Why, then, is there such a diversity of photosynthetic organisms?arrow_forwardThe 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_forward
- In 1770, Joseph Priestley performed a series of experiments to determine the reactants and products of photosynthesis. The diagram below shows the experimental conditions and results of two experiments performed by Priestley, named here as Experiment 1 and Experiment 2. From his experiments, Priestley concluded that plants restore to the air whatever breathing animals and candles remove. Joseph Priestly Photosynthesis Experiments and Results Experiment Results: - candle extinguished (went out) 1 - mouse died Experiment 2 Results: candle continued to burn mouse stayed alive Note: Experiment 1 and Experiment 2 were both performed in the presence of sunlight. The substance produced by the plant in Experiment 2, that keeps the candle burning and the mouse alive is O CO2 O 02 O H2O O C6H1206arrow_forwardIf 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?arrow_forwardAt the end of the first photosystem, an electron leaves a chlorophyll molecule.
