(burning of fossil fuels)
Photosynthesis (blank) (blank)
Plant & Animal Respiration (blank) (blank)


Lithosphere Atmosphere Biosphere Hydrosphere

Answer 1

Here’s how to fill in the blanks for the processes and their corresponding movement of carbon between different Earth systems:

### Process Moving carbon from the... to the...

1. **Decaying of animals and plants**
*From the* **Biosphere** *to the* **Lithosphere**
*(when organic matter decomposes, carbon is released into the soil)*

2. **Factory and Vehicle Emissions**
*From the* **Lithosphere** *to the* **Atmosphere**
*(burning of fossil fuels releases carbon dioxide into the air)*

3. **Photosynthesis**
*From the* **Atmosphere** *to the* **Biosphere**
*(plants take in carbon dioxide to produce glucose)*

4. **Plant & Animal Respiration**
*From the* **Biosphere** *to the* **Atmosphere**
*(organisms release carbon dioxide back into the air as they respire)*

### Summary

| Process | Moving carbon from the... | to the... |
|--------------------------------------------|----------------------------|---------------|
| Decaying of animals and plants | Biosphere | Lithosphere |
| Factory and Vehicle Emissions | Lithosphere | Atmosphere |
| Photosynthesis | Atmosphere | Biosphere |
| Plant & Animal Respiration | Biosphere | Atmosphere |
