Question

Match the cycle with processes that they use to recycle their material.

1. carbon cycle
nitrification, denitrification, fixation, assimilation, and ammonification
2. nitrogen cycle
photosynthesis, respiration, decomposition, and absorption
3. phosphorus cycle
weathering, erosion, decomposition, and absorption

Answer 1

Here’s the correct matching of cycles with the processes involved in recycling their materials:

1. **Carbon Cycle**
- **Processes**: photosynthesis, respiration, decomposition, and absorption

2. **Nitrogen Cycle**
- **Processes**: nitrification, denitrification, fixation, assimilation, and ammonification

3. **Phosphorus Cycle**
- **Processes**: weathering, erosion, decomposition, and absorption

So the matches are:
1 -> Photosynthesis, respiration, decomposition, and absorption
2 -> Nitrification, denitrification, fixation, assimilation, and ammonification
3 -> Weathering, erosion, decomposition, and absorption
