Find the incorrect statement from the following.

Options

A. Majority of Euglenoids are fresh water organisms found in statement water.
B. Slime moulds are saprophytic Protists.
C. All protozoans are heterotrophic and live as predators of saprophytes.
D. Dinoflagellates are mostly marine and photosynthetic.

Answer

To find the incorrect statement from the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- The statement claims that "the majority of euglenoids are freshwater organisms found in stagnant water."
- **Evaluation:** This statement is correct. Euglenoids, including Euglena, are primarily found in freshwater environments, particularly in stagnant water bodies.

2. **Analyze the Second Statement:**
- The statement claims that "slime molds are saprophytic protests."
- **Evaluation:** This statement is also correct. Slime molds are indeed saprophytic organisms, feeding on decaying organic matter.

3. **Analyze the Third Statement:**
- The statement claims that "all protozoans are heterotropic and live as predators of saprophytes."
- **Evaluation:** This statement is incorrect. While it is true that protozoans are heterotrophic, they can be predators, parasites, or saprophytes. The inclusion of "predators of saprophytes" is misleading because it implies that protozoans only consume saprophytes, which is not accurate. Some protozoans are parasites that cause diseases.

4. **Analyze the Fourth Statement:**
- The statement claims that "dinoflagellates are mostly marine and photosynthetic."
- **Evaluation:** This statement is correct. Dinoflagellates are primarily marine organisms and many of them are photosynthetic, contributing to marine ecosystems.

### Conclusion:
The incorrect statement among the options is the third statement: "all protozoans are heterotropic and live as predators of saprophytes."
