1) Rich description: The screenshot is from a YouTube video titled "Iceland's Deserts Are Turning Purple - here's why," featured on the channel MossyEarth. The scene displays a detailed diagram illustrating the nitrogen cycle with various components labeled throughout. At the top, "Atmospheric Nitrogen (N2)" is shown above a row of green plants, indicating the starting point of the cycle. The plants are central to the diagram, with arrows leading to processes like "Assimilation" and "Nitrogen-fixing bacteria living in legume root nodules." Other elements include "Denitrifying Bacteria," "Nitrates (NO3-)," "Ammonium (NH4+)," and "Nitrites (NO2-)," each connected by arrows that illustrate the flow and conversion of nitrogen through different stages. The diagram uses a mix of icons and text to convey its message, with a muted brown background simulating soil. The video caption at the bottom reads, "which will extract nitrogen from the air and fix it in the ground." This visual aims to educate viewers on ecological processes, specifically how nitrogen moves and transforms within ecosystems. 2) On-screen text block: - Title: "Iceland's Deserts Are Turning Purple - here's why" - Channel / profile: "MossyEarth" - Site / app: "YouTube" - Captions / subtitles: "which will extract nitrogen from the air and fix it in the ground."
