Black man's law of limiting factor is applicable to

Options

A. only photosynthesis
B. only respiration
C. only physical process
D. any biochemical process

Answer

**Step-by-Step Solution:**

1. **Understanding Blackman's Law of Limiting Factors**:
- Blackman's Law states that when a process (like photosynthesis) is conditioned by multiple factors, the rate of that process is limited by the factor that is in the shortest supply. This means that if one factor is lacking, it will slow down the entire process, regardless of the availability of other factors.

2. **Identifying the Context**:
- The question asks about the applicability of Blackman's Law. It is important to recognize that this law is primarily concerned with processes in plants, particularly photosynthesis.

3. **Listing the Factors**:
- In the context of photosynthesis, the factors that can limit the process include:
- Light intensity
- Carbon dioxide concentration
- Temperature
- Water availability
- Chlorophyll content

4. **Analyzing the Options**:
- The options given are:
- Only photosynthesis
- Only respiration
- Only physical processes
- Any biochemical processes
- Since Blackman's Law specifically addresses how the rate of photosynthesis is affected by limiting factors, it is clear that the law is applicable to photosynthesis.

5. **Conclusion**:
- Based on the understanding of Blackman's Law and the analysis of the options, the correct answer is that Blackman's Law of Limiting Factors is applicable to **only photosynthesis**.

**Final Answer**: Blackman's Law of Limiting Factors is applicable to **only photosynthesis**.
