Daniel wants to depict the stages of complete metamorphosis in their order of occurrence. Which arrow diagram represents the stages of complete metamorphosis in their order of occurrence?

Options

A. Egg `to` larva `to` pupa `to` adult
B. Egg`to` pupa`to` larva `to` adult
C. Larva `to`egg`to` pupa `to` adult
D. Pupa`to` egg `to` larva`to` adult

Answer

To depict the stages of complete metamorphosis in the correct order, we need to understand the process that insects undergo during their development. The stages of complete metamorphosis include:

1. **Egg**: The life cycle begins with the laying of eggs by the adult insect.
2. **Larva**: After hatching, the insect emerges as a larva (for example, a caterpillar in the case of butterflies). This stage is primarily focused on feeding and growth.
3. **Pupa**: Following the larval stage, the insect enters the pupal stage, where it undergoes transformation. This stage is often characterized by a protective casing (like a chrysalis for butterflies).
4. **Adult**: Finally, the insect emerges as an adult, ready to reproduce and continue the cycle.

Based on this understanding, the correct order of stages in complete metamorphosis is:

**Egg → Larva → Pupa → Adult**

Now, let's identify which arrow diagram represents this order:

1. **Option 1**: Egg → Larvae → Pupae → Adult (This is the correct order)
2. **Option 2**: Egg → Pupae → Larvae (This is incorrect)
3. **Option 3**: Larvae → Egg → Pupae → Adult (This is incorrect)
4. **Option 4**: Pupae → Adult (This is incorrect)

Thus, the correct arrow diagram that represents the stages of complete metamorphosis in their order of occurrence is **Option 1**: Egg → Larvae → Pupae → Adult.
