It is possible to predict the direction of succession.

Answer

**Step-by-Step Solution:**

1. **Understanding Ecological Succession**: Ecological succession refers to the process by which ecosystems change and develop over time. It involves a series of progressive changes in the species composition of an ecological community.

2. **Factors Influencing Succession**: The direction of succession is influenced by various environmental factors. These include:
- The type of environment (e.g., aquatic, terrestrial)
- The availability of resources such as nutrients and minerals in the soil
- The atmospheric conditions (whether the atmosphere is reducing or oxidizing)

3. **Positive vs. Negative Conditions**: The direction of succession can be predicted based on whether the environmental conditions are favorable (positive) or unfavorable (negative).
- If conditions are favorable, succession is likely to proceed in a certain direction.
- If conditions are unfavorable, succession may halt or change direction.

4. **Prediction of Succession**: While it is possible to predict the direction of succession based on the current environmental conditions, it is important to note that predictions are not certainties. They are based on observations and understanding of ecological principles.

5. **Conclusion**: Therefore, it is true that it is possible to predict the direction of succession, as it largely depends on the environmental conditions present at the time.

**Final Answer**: True, it is possible to predict the direction of succession.
