If the are non-limiting or unlimited conditions are provided than what what will happen to population
I. natality increase
II. Mortality decrease
III. Mortality increase
IV. Natality decrease
Choose the correct combination

Options

A. I and II
B. I and III
C. I and IV
D. IV and III

Answer

To solve the question regarding the effects of non-limiting or unlimited conditions on population dynamics, we need to analyze the terms involved: natality and mortality.

### Step-by-Step Solution:

1. **Understanding Natality and Mortality**:
- **Natality** refers to the birth rate of a population, essentially how many new individuals are born.
- **Mortality** refers to the death rate of a population, indicating how many individuals die.

2. **Conditions of Non-Limiting or Unlimited Resources**:
- When we say conditions are non-limiting or unlimited, it means that resources such as food, space, and other environmental factors are abundant and not restricted.

3. **Effects on Natality**:
- Under unlimited conditions, the availability of resources supports higher reproduction rates. Therefore, **natality will increase** as more individuals can survive to reproduce.

4. **Effects on Mortality**:
- With favorable conditions and abundant resources, the survival rate of individuals in the population will improve. Consequently, **mortality will decrease** because fewer individuals will die due to lack of resources or adverse conditions.

5. **Analyzing the Options**:
- I. Natality increase: **True**
- II. Mortality decrease: **True**
- III. Mortality increase: **False**
- IV. Natality decrease: **False**

6. **Correct Combination**:
- The correct combination of statements based on the analysis is I and II. Therefore, the answer is that both natality will increase and mortality will decrease under non-limiting conditions.

### Final Answer:
The correct combination is **I and II**.
