### Step-by-Step Solution:

1. **Understand the Types of Ecosystems**:
- Ecosystems can be classified into two main types: natural and man-made (artificial) ecosystems.
- Natural ecosystems exist in nature without human intervention, while man-made ecosystems are created by humans.

2. **Define Terrestrial Ecosystems**:
- Terrestrial ecosystems are those that are found on land. Examples include forests, grasslands, and deserts.

3. **Identify Characteristics of Natural Ecosystems**:
- Natural ecosystems are self-regulating and rich in biodiversity. They do not require human intervention for their sustainability.

4. **Identify Characteristics of Man-Made Ecosystems**:
- Man-made ecosystems are created by humans and require human intervention for their maintenance. They are designed to mimic natural ecosystems but are established for specific purposes, such as research, recreation, or preservation.

5. **Analyze the Given Options**:
- The options provided are:
- A) Forest (natural ecosystem)
- B) River (not a terrestrial ecosystem)
- C) Grassland (natural ecosystem)
- D) Botanical Garden (man-made ecosystem)
- E) Parks (man-made ecosystem)

6. **Select the Correct Answer**:
- Among the options, both "Botanical Garden" and "Parks" are examples of man-made terrestrial ecosystems because they are created for specific purposes and require human intervention. Therefore, the correct answer is **Botanical Garden and Parks**.

### Final Answer:
The example of a man-made terrestrial ecosystem is **Botanical Garden** and **Parks**.
