Explanation:

• For question 6: The x - axis labels (Newborn, Pre - reproductive age, Reproductive age, Post - reproductive age) clearly show that it represents the life stages of an organism.
• For question 7: Type II (Rodents) has a straight - line decline on the graph, indicating a steady decline at all life stages.
• For question 8: Type III (Fish, Insects, amphibians) has a sharp decline in the early life stages (Newborn to Pre - reproductive age).
• For question 9: The graph labels the dotted line as Type I: Human, so humans are Type I.

Answer:

1. Life stages of an organism.
2. Type II (Rodents).
3. Type III (Fish, Insects, amphibians).
4. Type I.
