**Diagram Explanation:**
The diagram provided illustrates a curve that represents the number of seeds consumed by a species based on seed size. The x-axis represents seed size, ranging from small to large, while the y-axis represents the number of seeds consumed.
1. **X-axis (Seed Size):** The horizontal axis depicts the size of the seeds, from small to large.
2. **Y-axis (Number of Seeds Consumed):** The vertical axis displays the number of seeds consumed.
**Graph Characteristics:**
- The curve shows a peak at the small seed size, indicating this species predominantly consumes small seeds.
- The number of seeds consumed decreases as seed size increases, showing intermediate consumption of medium-sized seeds and no consumption of large seeds.
**Tips for Drawing Models and Graphs:**
1. **Identify Variables:** Determine the habitat requirements and resources used by different species.
2. **Depict Proportionality:** The x-axis should detail the gradient of the resource, and the y-axis the number or proportion of resources used.
3. **Curve Interpretation:** Represent how the species' consumption habits vary across the resource gradient, indicating niche breadth and preferences.
For ease of comprehension, the visual elements should stay consistent with these principles to enhance understanding of ecological interactions and species resource use.
#### Additional Graph: Resource Use by Individuals
**Observation:**
A secondary graph is included below that visualizes the number of individuals using a resource. The x-axis represents the number of individuals, and the y-axis shows niche overlap, with varying data points plotted across the graph.
**Graph Details:**
- **X-axis (Number of Individuals):** Measures up to 400 individuals.
- **Y-axis (Niche Overlap):** Plotted against the number of individuals using the resources.
- The data points indicate varying degrees of resource use and competition in the population.

#### Model: Consumption of Seed Sizes by a Species
**Description:**
This section contains instructions for drawing a model representing the seed consumption habits of a particular species, focusing on the size of seeds consumed.
**Exercise:**
**MODEL**: Draw your own model for a species that consumes mostly small seeds, rarely medium-sized seeds, and never large seeds.
