(a) S - shaped
(b) J - shaped
(c) Initially J - shaped then S - shaped
(d) Initially S - shaped then J - shaped

Options

A. S - shaped
B. J - shaped
C. Initially J - shaped then S - shaped
D. Initially S - shaped then J - shaped

Answer

To determine the type of population growth curve for a population characterized by large size individuals, long life span, more parental care, and slow development, we can analyze the characteristics of different growth curves.

### Step-by-Step Solution:

1. **Understanding Population Characteristics**:
- The population has **large size individuals**: This often indicates a K-selected species, which typically have fewer offspring but invest more in raising them.
- **Long life span**: This suggests that individuals in this population survive longer, which is a trait of K-selected species.
- **More parental care**: This is another characteristic of K-selected species, where parents invest time and resources into raising their young.
- **Slow development**: This indicates that the species takes longer to reach reproductive maturity, which is typical for K-selected species.

2. **Identifying Growth Curves**:
- **J-shaped curve**: This curve represents exponential growth, typically seen in populations with unlimited resources and rapid reproduction. It is characteristic of r-selected species.
- **S-shaped curve (Sigmoid curve)**: This curve represents logistic growth, where the population grows rapidly at first (exponential phase), then slows down as it approaches the carrying capacity of the environment. This is typical for K-selected species.

3. **Applying Characteristics to Growth Curves**:
- Given the characteristics of the population (large size, long lifespan, more parental care, and slow development), it aligns with the traits of K-selected species.
- K-selected species typically exhibit an S-shaped growth curve because their population growth is limited by environmental factors and carrying capacity.

4. **Conclusion**:
- Based on the analysis, the type of population growth curve for the described population is **S-shaped** (Option A).

### Final Answer:
The type of population growth curve will be **(a) S-shaped**.
