Photosynthesis, Respiration and Carbon Cycle Review

The diagram illustrates a cellular process that occurs in autotrophic organisms. Which statement accurately identifies the process and the role it plays in the environment

• The process is cellular respiration, and it converts radiant energy into inorganic compounds which are consumed by herbivores.

• The process is cellular respiration, and it is the primary source of radiant energy in the environment.

• The process is photosynthesis, and it is important in the recycling of the atmospheric carbon dioxide.

• The process is photosynthesis, and it uses organic compounds and water to produce energy which is released as heat.

Based on the diagram, what is disrupting the natural balance of the carbon cycle?

• greater absorption of carbon dioxide by oceans

• release of carbon dioxide by fossil fuel burning and land use

• greater absorption of carbon dioxide by land than by oceans

• release of carbon dioxide by vegetation and land use.

If humans replace the forest with a factory, how will this affect the carbon cycle in the area?

• The forest is a carbon sink and with its removal ,there will be less carbon released into the atmosphere.

• The forest is a carbon source, and with its removal, there will be more carbon released into the atmosphere.

• The forest is a carbon sink, and with its removal there will be more carbon released into the atmosphere.

• The forest is a carbon source, and with its removal, there will be more carbon released into the hydrosphere.

Fossil fuels like coal, oil and natural gar are widely used across the world to run vehicles, power electricity plants, and heat buildings. Rapid growth in the human population is causing an exponential rise in the use of fossil fuels. Increases use of these fossil fuels is not only depleting the Earth of these nonrenewable natural resources, it is also releasing huge amounts of carbon dioxide into the air.

How is the release of huge amounts of carbon dioxide affecting the environment?

• It's is causing a decrease in the grass cover of the land.

• It is causing a rise in the average temperature of the planet.

• It is resulting in the spread of diseases among aquatic animals.

• It is resulting in the spread of invasive, non-native aquatic animals

Students conducted an experiment to determine if water temperature affects the rate of photosynthesis in pondweed. Which conclusion can be defended based upon this data?

• Photosynthesis in pondweed is at its highest rate at 30C

• Photosynthesis in pondweed is at its highest rate of productivity at 40C

• The rate of photosynthesis increases as the temperature increases.

• The rate of photosynthesis decreases as the temperature increases.
