A Phagotrophs take solid nutrition.
R Photosynthetic organisms are called Producers.

Options

A. If both As and R are correct and R is correct explanation of As
B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

To solve the assertion and reason question, we can follow these steps:

### Step 1: Analyze the Assertion
The assertion states: "Phagotrophs take solid nutrition."
- **Explanation**: Phagotrophs are organisms that consume solid food particles. They are a type of heterotroph that ingests solid organic matter for energy. This statement is true.

### Step 2: Analyze the Reason
The reason states: "Photosynthetic organisms are called Producers."
- **Explanation**: Photosynthetic organisms, primarily plants, utilize sunlight to produce their own food through the process of photosynthesis. They are indeed referred to as producers because they form the base of the food chain. This statement is also true.

### Step 3: Determine the Relationship Between Assertion and Reason
- While both statements are true, we need to assess whether the reason provided is a correct justification for the assertion.
- **Analysis**: The assertion about phagotrophs does not depend on or relate to the reason about photosynthetic organisms being producers. They are two separate concepts in ecology.

### Step 4: Conclusion
- Since both the assertion and reason are true, but the reason does not explain the assertion, the correct answer is that both statements are correct, but the reason is not the correct explanation for the assertion.

### Final Answer
Both assertion and reason are correct, but reason is not the correct explanation for the assertion. Therefore, the answer is option B.
