Intraspecific competition is competition among

Options

A. different species
B. individuals of population
C. individuals of a community
D. population and their regulatory factor

Answer

**Step-by-Step Solution:**

1. **Understanding Intraspecific Competition**:
- Intraspecific competition refers to the competition that occurs among individuals of the same species. This is a key concept in population ecology.

2. **Defining Key Terms**:
- The prefix "intra-" means "within" or "inside," indicating that the competition is happening within a single species.
- In contrast, "inter-" refers to competition between different species.

3. **Identifying the Context**:
- Intraspecific competition typically occurs when individuals of the same species compete for limited resources such as food, space, or mates.

4. **Effects of Intraspecific Competition**:
- This competition can lead to a reduction in fitness for both competing individuals. However, the individual that is more fit (better adapted to the environment) is likely to survive and reproduce.

5. **Examples**:
- An example of intraspecific competition could be two male birds of the same species competing for a mate in a specific area.

6. **Conclusion**:
- Therefore, the correct answer to the question "Intraspecific competition is competition among" is "individuals of a population" (which refers to individuals of the same species).

**Final Answer**: Intraspecific competition is competition among individuals of a population.
