Explanation

To solve the question, we need to fill in the blanks in the given statements with the correct terms related to biodiversity and conservation. Let's analyze each statement step by step.

### Step-by-Step Solution:

1. **Statement (i)**: "Species of plants and animals that are found exclusively in a particular area and do not occur naturally anywhere else are called _______ species."
- The correct term to fill in the blank is **endemic**. Endemic species are those that are native to a specific location and are not found naturally anywhere else.
