To explain: The reason that consumption of a large amount of carbon dioxide by living trees does not make much contribution in the reduction of global warming.
Concept introduction:
The earth’s surface has enormous amount of carbon. It moves through the biosphere in the processes mediated by photosynthetic plants on land and in sea. This is represented as the carbon cycle, which involves two main processes namely photosynthesis and respiration. The photosynthesis process involves fixation of atmospheric carbon in plants to form organic molecules such as sugars required for life processes. Respiration is the process through which carbon is returned to the atmosphere from dead plants in the form of carbon dioxide.

- As CO2 concentrations increase in the atmosphere, biologists continue to explore the role of respiration from plants as a small but potentially important contribution beyond fossil fuel combustion. The data in the Table were collected from the leaf of a sagebrush plant from a semiarid ecosystem in Wyoming, enclosed in a chamber that measures the rate of CO2 exchange. The respiration rate is the amount of CO2 in micromoles lost by the leaf per square meter per second, which results in the negative numbers. The temperature values are from the leaves as they are heated or cooled during the measurements.

But 12 O atoms are evolved as 6 O2, and only 6 O atoms appear as 6 H2O in the equation. Also, 6 CO2 have 12 O Atoms, yet there are only 6 O atoms in C6H12O6. How can you account for these discrepancies? (Hint: Consider the partial reactions of photosynthesis: ATP synthesis, NADP reduction, photolysis of water, and the overall reaction for hexose synthesis in the Calvin-Benson cycle)arrow_forwardScientific evidence indicates that the CO2 added to the air by the burning of wood and fossil fuels is contributing to global warming, a rise in global temperature. Tropical rain forests are estimated to be responsible for approximately 20% of global photosynthesis, yet the consumption of large amounts of CO2 by living trees is thought to make little or no net contribution to reduction of global warming. Why might this be? (Hint: What processes in both living and dead trees produce CO2?) *arrow_forward
- Tropical rainforest covers only about 3% of earth's surface, but they are estimated to be responsible for more than 20% of global photosynthesis. For this reason, rainforests are often referred to as the “lungs' ' of the planet, providing O2 for life all over earth. However, most experts believe that rainforests make little or no net contribution to global O2 production. From your knowledge of photosynthesis and cellular respiration, can you explain why they might think this? ( Hint: what happens to the energy stored as sugars in the body of a plant when that plant dies or parts of it are eaten by animals?)arrow_forwardPhotosynthesis and cellular respiration are related to each other through the cycling of carbon in various forms as it moves through different living and nonliving systems. only the breaking down of molecules which support chemicals reactions that occur in living things. their reliance on processes like fossilization, combustion, feeding, etc. to move chemicals needed to support life. A and B A and Carrow_forwardPart B Photosynthesis plays an important role in maintaining life in most ecosystems on Earth because it has an impact on how organisms obtain their energy. In your science journal, write a claim that supports the idea that photosynthesis helps sustain life on Earth, and support that claim with at least one piece of evidence. Use the rubric below to assist you with your response. Criteria Scale Makes Claim about Photosynthesis and Supports Claim with Evidence 2 This response includes both a claim about photosynthesis and its importance, and supports the claim with one piece of factual evidence. 1 This response either lacks both a claim and a piece of evidence, or contains a faulty claim or irrelevant/faulty evidence. 0 This response lacks the required components for partial credit.arrow_forward
