Options

A. Pond
B. Crop field
C. Lake
D. Forest

Answer

To determine an example of an artificial ecosystem from the provided options, we can follow these steps:

### Step 1: Understand the Definition of an Artificial Ecosystem
An artificial ecosystem is a human-made environment that includes living organisms (plants, animals, and humans) interacting with each other and their surroundings.

### Step 2: Identify Examples of Artificial Ecosystems
Common examples of artificial ecosystems include:
- Zoos
- Botanical gardens
- Parks
- Aquariums
- Agricultural fields

### Step 3: Analyze the Given Options
Now, we need to look at the options provided in the question and identify which one fits the definition of an artificial ecosystem.

### Step 4: Eliminate Natural Ecosystems
We should also recognize that natural ecosystems, such as lakes and forests, do not qualify as artificial ecosystems since they are not created or significantly modified by humans.

### Step 5: Select the Correct Example
From the examples we identified and the options provided, we can select the one that is clearly a human-made environment. For instance, if "zoo" is one of the options, it would be the correct answer as it is a controlled environment created by humans for the purpose of housing and displaying animals.

### Final Answer
The correct answer is the example that represents a human-made environment, such as a zoo or a garden.
