The organisms which attack dead animals are :

Options

A. First link of the food chain and are known as primary producers
B. Second link of the food chain and are herbivorous
C. Third link of the food chain and are tertiary consumers
D. The end of food chain and are decomposers

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about organisms that attack dead animals. This indicates that we are looking for a specific group of organisms that play a role in the decomposition process.

2. **Identifying the Role of Organisms**: Organisms that attack dead animals are involved in obtaining nutrition from these dead organisms. They play a crucial role in breaking down organic matter.

3. **Defining Decomposers**: The organisms that feed on dead animals and other decomposing organic matter are known as decomposers. They include bacteria, fungi, and certain invertebrates.

4. **Position in the Food Chain**: Decomposers are located at the end of the food chain. They are essential for recycling nutrients back into the ecosystem, allowing for the continuation of life.

5. **Analyzing Options**: If we consider the options given in the question:
- Option 1 refers to primary producers, which are not correct as they are the first link in the food chain.
- Option 2 refers to secondary consumers, which also do not fit the description.
- Option 3 suggests they are at the end of the food chain, which aligns with our understanding.
- Therefore, the correct answer is option 3, which identifies them as decomposers.

**Final Answer**: The organisms that attack dead animals are called decomposers.
