When feeding efficiency of one species is reduced in presence of the other species even if the resources are abundant , it is called -

Answer

To solve the question "When feeding efficiency of one species is reduced in presence of the other species even if the resources are abundant, it is called -", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question is asking about a specific type of interaction between two species where one species' feeding efficiency is negatively impacted by the presence of another species, despite the availability of resources.

2. **Identify Types of Interactions**: In ecology, there are various types of interactions between species, including:
- Competition
- Predation
- Commensalism
- Amensalism
- Mutualism
- Parasitism

3. **Focus on Competition**: Since the question mentions that one species' feeding efficiency is reduced, we should focus on competition. In ecological terms, competition occurs when two species vie for the same resources, which can lead to a decrease in the feeding efficiency of one or both species.

4. **Differentiate Types of Competition**: There are two main types of competition:
- **Exploitation Competition**: Where species compete indirectly through the consumption of shared resources.
- **Interference Competition**: Where one species directly interferes with another's ability to access resources.

5. **Conclude with the Correct Term**: Given that the question specifies a reduction in feeding efficiency due to the presence of another species, this scenario is best described as **interference competition**. This is because one species is actively interfering with the foraging or feeding activities of the other species.

### Final Answer:
The correct term for the situation described in the question is **interference competition**.
