Questions about the Nutrient Cycles poster

What’s on the Nutrient Cycles poster?
A 6-row table: Cycle · Processes. The key processes in each cycle. Carbon — Photosynthesis, respiration, decomposition, combustion; Nitrogen fixation — N₂ → ammonia, by bacteria or lightning; Nitrification — Ammonia → nitrite → nitrate; Assimilation — Plants take up nitrate; Ammonification — Decomposers release ammonia; Denitrification — Nitrate → N₂, anaerobic. Nitrogen is 78% of the atmosphere and unusable by plants as N₂. Fixation by bacteria is the bottleneck for all life.
Who is the Nutrient Cycles poster for?
Nutrient Cycles belongs to the Biology section rather than to a school year, because life science is not something one grade owns. Anyone learning ecology can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Nutrient Cycles poster?
Energy flows through and is lost. Matter cycles and is reused. A wall chart earns its place by being glanceable from where the work is happening, so Nutrient Cycles belongs on the wall where that life science work actually happens, within glancing distance, rather than filed away.
What other posters go with Nutrient Cycles?
Measuring Biodiversity, Carbon in Ecosystems and Climate & Ecosystems sit alongside Nutrient Cycles in the Biology section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Measuring BiodiversityCarbon in EcosystemsClimate & Ecosystems
Is the Nutrient Cycles poster free to download and print?
Yes. Nutrient Cycles downloads as a free PDF with no account, no email and no watermark, like everything else in the Biology section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
What size does the Nutrient Cycles poster print at?
Nutrient Cycles is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Nutrient Cycles loses nothing.Printing guide
