What process is being described by this figure?

2. competition
3. predation
4. niche differentiation
![The figure illustrates the concept of "character displacement" over time through two graphs, demonstrating how natural selection influences species competing for the same resources.
**Graph Explanation:**
- **Top Graph (Time 1):**
- The x-axis represents the "Niche (range of resources used)," and the y-axis represents the "Number of individuals using resource."
- Two species, labeled Species 1 and Species 2, are shown with overlapping niches, indicating competition for the same resources. Species 1 has decreasing fitness as it overlaps with Species 2, resulting in "Low fitness" in the overlapping area, while higher fitness is observed where there is less competition.
- **Bottom Graph (Time 2):**
- Again, the x-axis represents the "Niche (range of resources used)," and the y-axis indicates the "Number of individuals using resource."
- Over time, natural selection acts against individuals of both species in the overlapping niche area. As a result, Species 1 and Species 2 have shifted to reduce overlap, now occupying distinct niches. This results in less competition and greater "High fitness" for both species separately due to niche differentiation.
**Explanation of Process:**
The figure demonstrates the process of character displacement where species evolve distinct traits to minimize competition for resources. Over time, natural selection reduces niche overlap, allowing coexisting species to maximize their fitness in distinct ecological niches.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F161a8a2d-c3b8-424f-bacd-f932b9de1b74%2F36e26ceb-e784-4cde-b42e-08c5b66664e3%2Fxeh02h_processed.jpeg&w=3840&q=75)
