Camel, Cattle, sheep & goats can digest cellulose by virtue of

Options

A. Their enzyme
B. Symbiotic E. coli
C. Symbiotic bacteria & protozoa
D. Symbiotic virus & nematods

Answer

To answer the question "Camel, Cattle, Sheep & Goats can digest cellulose by virtue of?", we need to understand the digestive system of these animals, which are known as ruminants.

### Step-by-Step Solution:

1. **Identify the Organism Type**: Recognize that camels, cattle, sheep, and goats are ruminants. Ruminants are animals that have a specialized stomach structure that allows them to digest cellulose from plant materials.

2. **Understand the Stomach Structure**: Ruminants possess a multi-chambered stomach, which includes the rumen, reticulum, omasum, and abomasum. The rumen is the largest chamber and plays a critical role in digestion.

3. **Role of Microorganisms**: In the rumen, there are various microorganisms, including bacteria, protozoa, and fungi, that help in breaking down cellulose. These microorganisms are essential for the fermentation process.

4. **Identify Key Microorganisms**: The specific microorganisms that assist in cellulose digestion include symbiotic bacteria such as *Ruminococcus albus* and *Ruminococcus flavefaciens*. These bacteria help to break down cellulose into simpler sugars that the ruminants can absorb and utilize.

5. **Evaluate the Options**:
- Option 1: "Dear Enzymes" - Incorrect, as ruminants rely on microorganisms rather than just enzymes.
- Option 2: "Symbiotic E.coli" - Incorrect, as E.coli is primarily found in the human intestine and is not the main contributor to cellulose digestion in ruminants.
- Option 3: "Symbiotic Bacteria and Protozoa" - Correct, as these microorganisms are essential for cellulose digestion in ruminants.
- Option 4: "Symbiotic virus and Nematodes" - Incorrect, as viruses and nematodes are not involved in cellulose digestion and can often cause diseases.

6. **Conclusion**: The correct answer is that camels, cattle, sheep, and goats can digest cellulose by virtue of symbiotic bacteria and protozoa present in their rumen.

### Final Answer:
Camel, cattle, sheep, and goats can digest cellulose by virtue of **symbiotic bacteria and protozoa**.
