Biology infographic cycle diagram for powerpoint poster

Educational infographic poster titled "Biology Cycle Diagram" in landscape layout, designed for classroom PowerPoint use, with sharp readable sans-serif text labels and clean numbered callouts. Create a detailed 8-step circular cycle infographic in the nature / biology domain, with each stage arranged around a central hub and connected by bold curved arrows, dotted guide lines, and large sequence numbers 1-8 to clearly show continuous flow.

1. heading: "Sunlight Input", caption: "Solar energy powers the start of the biological cycle.", visual: bright sun icon with rainbow light rays striking green leaves and a small energy arrow entering the cycle.
2. heading: "Plant Growth", caption: "Plants capture light and build organic matter.", visual: cutaway of a leaf with visible veins, chloroplast-style micro-diagrams, roots in soil, and upward growth arrows.
3. heading: "Herbivore Feeding", caption: "Animals consume plants and transfer stored energy.", visual: simplified deer or rabbit silhouette eating grass, with internal cutaway arrows showing food moving through the body.
4. heading: "Predator Transfer", caption: "Energy moves through the food chain to higher consumers.", visual: owl or fox icon with a directional arrow from prey to predator, plus a small trophic-level pyramid inset.
5. heading: "Respiration", caption: "Organisms release energy, carbon dioxide, and water.", visual: technical cutaway diagram with lungs/leaf stomata style gas exchange arrows, oxygen in and carbon dioxide out.
6. heading: "Decomposition", caption: "Fungi and microbes break down dead material into nutrients.", visual: soil cutaway with mushrooms, bacteria icons, earthworms, and decomposing leaves turning into nutrient particles.
7. heading: "Nutrient Return", caption: "Minerals re-enter soil and water for reuse.", visual: cross-section of soil layers with labeled nutrient symbols moving toward roots and groundwater via dotted arrows.
8. heading: "Cycle Renewal", caption: "Recycled resources support new plant growth again.", visual: sprouting seedling emerging from enriched soil, with a closing arrow looping back to the sunlight and plant stage.

Center element: a clean circular hub diagram labeled "Biological Cycle" with small icons for sun, leaf, animal, microbe, water droplet, and soil minerals arranged as a legend ring. Use clear clockwise flow with thick arrows between each numbered stage, subtle dotted connectors from captions to visuals, and small side legend boxes for "Energy Flow" and "Nutrient Recycling".

Visual style: cutaway technical diagram, educational editorial infographic, detailed but student-friendly, vibrant rainbow palette distributed harmoniously across stages (red, orange, yellow, green, cyan, blue, violet accents), crisp white background, high contrast for readability, clean English typography in sans-serif, balanced classroom-science mood, magazine-grade editorial illustration, vector-clean lines, no photographic textures.

All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no watermarks Render labels and headings in clean English typography (sans-serif). No real-brand logos, no copyrighted characters, no people that could be identified, no graphic medical content. If the topic touches a regulated domain (medicine, finance, law), keep the explanation conceptual and add no specific dosages, prices or legal advice.
