22
carbon cycle
put the correct process that is happening over what represents that process in the carbon cycle.
image of carbon cycle diagram with labels like terrestrial life, aquatic life respiration or decomposition, diffusion,sedimentation (slow)

Explanation:

To solve this, we analyze the carbon cycle components:

Step1: Identify Photosynthesis

The arrow from \( \text{CO}_2 \) to plants (trees, aquatic life) represents photosynthesis (plants use \( \text{CO}_2 \), sunlight, and water to make glucose, releasing \( \text{O}_2 \)).

Step2: Identify Respiration

Arrows from terrestrial/aquatic life to \( \text{CO}_2 \) are respiration (organisms release \( \text{CO}_2 \) by breaking down glucose).

Step3: Identify Combustion (Fossil Fuels)

The factory and fossil fuel reservoir (black) connect to \( \text{CO}_2 \) via combustion (burning fossil fuels or biomass releases \( \text{CO}_2 \)).

Step4: Identify Decomposition

Arrows from dead organisms to soil/plants: decomposition (decomposers break down organic matter, releasing \( \text{CO}_2 \) or nutrients).

Step5: Identify Diffusion

The water-\( \text{CO}_2 \) exchange is diffusion ( \( \text{CO}_2 \) dissolves in water or is released from water).

Step6: Identify Sedimentation (Slow Cycle)

The "sedimentation (slow)" arrow shows organic matter settling into sediment, forming fossil fuels over time.

Answer:

• The box near plants (trees/aquatic) → Photosynthesis
• Boxes near animals/plants → Respiration
• Box near factory/fossil fuel → Combustion (or Fossil Fuel Combustion)
• Box near dead organisms/soil → Decomposition
• The \( \text{CO}_2 \)-water exchange → Diffusion
• The "sedimentation (slow)" path → Sedimentation (forms fossil fuels over time)

(Assign each blank based on the diagram’s labels: e.g., the tree-related blank is Photosynthesis, animal-related is Respiration, factory-related is Combustion, etc.)
