7: Why do we use models to show the carbon cycle?

Answer 1

Step-by-step explanation:

1. During photosynthesis, six molecules of carbon dioxide react with six molecules of water to produce glucose (C6H12O6) and six molecules of oxygen gas (O2).

2. The hydrosphere brings carbon into the ocean reservoir.

3. The largest source of stored carbon can be found in rocks and sediments, such as limestone and fossil fuels.

4. The key macromolecules made out of carbon are carbohydrates, lipids, proteins, and nucleic acids.

5. Photosynthetic chemical reactions occur in the chloroplasts of plant cells, specifically in the thylakoid membranes and stroma.

Answer 2

Answer: 1: During photosynthesis, six molecules of carbon dioxide react with six molecules of water to produce glucose (a sugar molecule) and six molecules of oxygen.

2: The hydrosphere brings carbon into the oceanic reservoir. Carbon dioxide dissolves in water, forming carbonic acid and other carbon-containing compounds, which contribute to the carbon content in the ocean.

3: The largest source of stored carbon can be found in sedimentary rocks, such as limestone, which contain carbonate minerals formed from the accumulation of marine organisms' remains over long periods.

4: The key macromolecules made out of carbon are carbohydrates, lipids, proteins, and nucleic acids. Carbohydrates and lipids (fats) are examples of carbon-based molecules that play essential roles in energy storage and structural components within organisms.

5: Photosynthetic chemical reactions occur in specialized cell structures called chloroplasts, primarily in the leaves of plants. Chloroplasts contain chlorophyll, a pigment that captures sunlight and drives the chemical reactions of photosynthesis.

6:

a. Atmosphere

b. Hydrosphere (oceans, lakes, rivers)

c. Biosphere (living organisms and organic matter)

d. Geosphere (sedimentary rocks, fossil fuels, soil)

7: Models are used to show the carbon cycle because it is a complex system involving multiple interconnected processes and reservoirs. Models provide a simplified representation that helps scientists and researchers understand the dynamics of carbon cycling, track carbon fluxes, and assess the impacts of various factors on the carbon cycle. Models allow for experimentation, predictions, and scenario analysis, helping us better comprehend the intricate nature of the carbon cycle and its implications for Earth's climate and ecosystems.
