B. Active cooperation between two species
C. Two different parasites on same food
D. Sharing resources between two species

Answer

**Step-by-Step Text Solution:**

1. **Definition of Niche**: The term "niche" in ecology refers to the role and position a species has in its environment. This includes how it gets its energy and nutrients, where it lives, and how it interacts with other organisms and the abiotic factors in its environment.

2. **Components of a Niche**: An ecological niche encompasses various aspects such as:
- **Functional Role**: This includes the activities of the organism, such as reproduction and locomotion.
- **Resource Utilization**: The types of food and habitat the organism uses to survive.

3. **Understanding Niche Overlap**: Niche overlap occurs when two or more species share the same niche or resources in an ecosystem. This means that they utilize similar resources or occupy similar roles in the environment.

4. **Example of Niche Overlap**: To illustrate niche overlap, consider a scenario where you live in a house (your niche). You have your own space and resources (food, toys, etc.). When a cousin comes to stay, you both have to share these resources. This sharing of resources is analogous to niche overlap in ecology, where two species must compete for the same resources.

5. **Implications of Niche Overlap**: When niches overlap, it can lead to competition between species. This competition can affect population dynamics and community structure, as species may compete for food, space, or other resources.
