Which of the following help in communication with the other members of the same species?

Options

A. Hormones
B. Automones
C. Pheromones
D. Autocoids

Answer

To answer the question "Which of the following help in communication with the other members of the same species?" we need to analyze the options provided: hormones, automons, pheromones, and autokites.

### Step-by-Step Solution:

1. **Understanding Hormones**:
- Hormones are chemical messengers produced in the body that travel through the bloodstream to target organs.
- They primarily function in regulating physiological processes and do not facilitate communication between individuals of the same species.

**Hint**: Think about how hormones function in the body and their role in internal regulation rather than external communication.

2. **Evaluating Automons**:
- The term "automons" does not refer to any recognized biological or chemical communication method. It seems to be a misnomer or an incorrect option.
- Therefore, automons are not involved in communication between members of the same species.

**Hint**: Consider whether the term is commonly used in biology or if it seems out of place.

3. **Examining Pheromones**:
- Pheromones are chemical substances secreted by an individual and detected by others of the same species.
- They play a crucial role in communication, influencing behaviors such as mating, marking territory, and signaling danger.
- Pheromones are specifically designed to elicit a social response from other members of the species.

**Hint**: Recall examples of pheromones in nature, such as those used by ants or moths for attracting mates.

4. **Considering Autokites**:
- Similar to automons, "autokites" is not a recognized term in biological communication.
- This option does not pertain to communication among species members.

**Hint**: Reflect on whether this term is familiar in the context of biology or animal behavior.

### Conclusion:
Based on the analysis, the correct answer to the question is **pheromones**. They are the only option that facilitates communication between members of the same species.
