Identify the vertebrate group of animals characterised by crop and gizzard in its digestive system

Options

A. amphibia
B. reptilia
C. aves
D. osteichthyes

Answer

To solve the question, we need to identify the vertebrate group of animals that has a digestive system characterized by the presence of a crop and gizzard. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understand the Terms**:
- **Crop**: A pouch-like structure in the digestive system where food is stored and softened before it moves to the stomach.
- **Gizzard**: A muscular part of the stomach that grinds food, often containing stones or grit to aid in the grinding process.

2. **Analyze the Options**:
- **Option A: Amphibia**: Amphibians (like frogs) do not have a crop and gizzard; they have a simpler digestive system.
- **Option B: Reptilia**: Reptiles (like snakes and lizards) also do not possess a crop and gizzard in their digestive systems.
- **Option C: Apes**: Apes (which are primates) have a more complex digestive system, including a crop and gizzard.
- **Option D: Osteopaths**: This term seems to be a misrepresentation; it might refer to Osteichthyes (bony fish), which do not have a crop and gizzard.

3. **Identify the Correct Group**:
- After analyzing the options, we find that **Apes** are the only group listed that has both a crop and gizzard in their digestive system.

4. **Final Answer**:
- Therefore, the vertebrate group characterized by a crop and gizzard in its digestive system is **Option C: Apes**.
