Which of the following organisms and trophic levels is mismatched?

Options

A. Algae-producer
B. Phytoplankton-primary consumer
C. Fungi-detritivore
D. Bob cat-secondary consumer

Answer

To determine which organism and trophic level is mismatched, we need to analyze each option provided. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand Trophic Levels
Trophic levels are the different levels in a food chain, where organisms are categorized based on their feeding relationships. The primary levels are:
- **Producers**: Organisms that produce their own food (e.g., plants, algae).
- **Primary Consumers**: Herbivores that consume producers.
- **Secondary Consumers**: Carnivores that eat primary consumers.
- **Decomposers**: Organisms that break down dead organic matter (e.g., fungi, bacteria).

### Step 2: Analyze Each Option
1. **Algae - Producers**:
- Algae are indeed producers as they perform photosynthesis and produce their own food. This match is correct.

2. **Fungi - Decomposers**:
- Fungi are decomposers that break down dead organic matter. This match is also correct.

3. **Bacteria - Decomposers**:
- Similar to fungi, bacteria decompose organic material. This match is correct.

4. **Bobcat - Secondary Consumer**:
- Bobcats are carnivores that feed on primary consumers (like rabbits). This match is correct.

### Step 3: Identify the Mismatched Pair
Upon reviewing the options, it appears that all the matches provided in the question are correct. However, the video transcript suggests that there was confusion regarding the classification of zooplankton, which are primary consumers that feed on phytoplankton (producers).

### Conclusion
The mismatched organism and trophic level is not explicitly listed in the options provided, but based on the context of the video, it could be inferred that the mention of zooplankton as a primary consumer could have been the source of confusion.

### Final Answer
The mismatched organism and trophic level is **zooplankton - primary consumers** (if it was incorrectly matched in the options).
