Which competition is more intense ?

Options

A. intraspecific competition
B. interspecific competition
C. both 1 and 2
D. predation

Answer

To determine which type of competition is more intense, we need to understand the two main types of competition: intraspecific competition and interspecific competition.

### Step-by-Step Solution:

1. **Define Intraspecific Competition**:
- Intraspecific competition occurs between individuals of the same species. This type of competition is often more intense because individuals compete for the same resources such as food, space, and mates.

2. **Define Interspecific Competition**:
- Interspecific competition occurs between individuals of different species. While species may compete for similar resources, the competition is generally less intense because the species involved may have different needs or adaptations.

3. **Analyze the Intensity of Competition**:
- Intraspecific competition is typically more intense than interspecific competition. This is because individuals of the same species have identical needs and thus compete more directly for the same resources.

4. **Consider the Impact of Competition**:
- Intraspecific competition can lead to a decrease in feeding efficiency and overall fitness of individuals due to the high demand for limited resources. In contrast, interspecific competition may not always lead to such a significant decrease in efficiency, as species may utilize different resources or occupy different niches.

5. **Conclusion**:
- Based on the analysis, we conclude that intraspecific competition is more intense than interspecific competition. Therefore, the answer to the question is that intraspecific competition is the more intense form of competition.

### Final Answer:
Intraspecific competition is more intense than interspecific competition.
