Answer

To answer the question "A succession that does not follow the natural course due to human activity is," we need to analyze the types of ecological successions and their definitions. Here's a step-by-step breakdown of the solution:

### Step 1: Understand Ecological Succession
Ecological succession is the process by which ecosystems change and develop over time. It can be classified into primary and secondary succession.

### Step 2: Identify Types of Succession
1. **Primary Succession**: This occurs in lifeless areas where soil has not yet formed (e.g., after a volcanic eruption).
2. **Secondary Succession**: This occurs in areas where a disturbance has destroyed an existing ecosystem but soil and some organisms still remain (e.g., after a forest fire).

### Step 3: Define Human Impact on Succession
Human activities can disrupt natural ecological processes. When human actions interfere with the natural progression of succession, it can lead to altered ecosystems.

### Step 4: Identify the Correct Term
- **Plagocere**: This term refers to a succession that does not follow the natural course due to human activity. It signifies that human intervention has disrupted the natural development of communities.
- **Subcere**: Refers to secondary succession that is interrupted by natural or human activities.
- **Precere**: Refers to the serial community progressing towards a climax community.
- **Aseer**: Refers to the absence of succession.

### Conclusion
The correct answer to the question is **Plagocere**, as it specifically indicates a succession disrupted by human activity.
