To solve the question regarding extrinsic and intrinsic growth, we can follow these steps:
### Step 1: Understand the Definitions
- **Extrinsic Growth**: This type of growth occurs from external factors or influences. It is typically associated with non-living entities where growth is not due to internal processes.
- **Intrinsic Growth**: This type of growth occurs from internal processes and is characteristic of living organisms. It involves cell division and metabolic activities that lead to an increase in size or number.
### Step 2: Identify Examples of Extrinsic Growth
- Look for examples of extrinsic growth in the options provided. Non-living entities like mountains, boulders, and sand dunes exhibit extrinsic growth, as they can increase in size due to external factors like erosion, sediment deposition, etc.
### Step 3: Identify Examples of Intrinsic Growth
- Now, look for examples of intrinsic growth. Living organisms such as humans, mango trees, and houseflies exhibit intrinsic growth, as they grow from within through biological processes like cell division and metabolism.
### Step 4: Match the Options
- Based on the definitions and examples:
- **Extrinsic Growth**: Mountains, boulders, sand dunes (non-living)
- **Intrinsic Growth**: Humans, mango trees, houseflies (living)
### Step 5: Conclusion
- The correct answer to the question is that extrinsic growth is found in non-living entities (like mountains and boulders), while intrinsic growth is found in living entities (like humans and houseflies).
### Final Answer
Extrinsic growth is found in non-living entities (e.g., mountains, boulders), and intrinsic growth is found in living entities (e.g., humans, houseflies).
