### Transcription and Explanation of Absorption Spectra Diagram

**Text from the Image:**
"Use the figure below to match the pigments’ description with their absorption spectra."

**Description of Diagram:**

The graph presented is an absorption spectra diagram which plots the "Amount of light absorbed" against "Wavelength in nm" (nanometers). The spectral range spans from 400 nm to 700 nm, corresponding to the visible light spectrum. At the bottom, the diagram includes a color gradient ranging from violet (~400 nm) to red (~700 nm).

**Graph Details:**

1. **Curve A** (Green Line):
   - Peaks at the blue region around 450 nm.
   - Represents a pigment strongly absorbing in the blue-violet end of the spectrum.

2. **Curve B** (Yellow Line):
   - Peaks around the green-blue region close to 500 nm.
   - Indicates absorption primarily in the green range.

3. **Curve C** (Red Line):
   - Peaks around the orange to red region near 650 nm.
   - Reflects a pigment with maximum absorption at the red end.

4. **Curve D** (Blue Line):
   - Peaks in the green region around 550 nm and again in the red region.
   - Shows dual absorption peaks characteristic of some pigments that absorb in both the green and red areas.

5. **Curve E** (Cyan Line):
   - Peaks sharply close to 700 nm in the far-red region.
   - Represents absorption primarily at the very end of the visible spectrum.

This diagram represents different pigments based on their ability to absorb light at various wavelengths, essential for understanding photosynthesis and other biological processes involving light absorption. Each curve corresponds to a specific pigment, allowing interpretation of their absorption capabilities across the visible spectrum.
