What’s on the Ecosystems poster
A definition and 6 facts worth remembering.
An ecosystem is every living thing in an area plus the non-living things they depend on — soil, water, air and sunlight.
- Producers make their own food from sunlight.
- Consumers eat other living things — herbivores, carnivores, omnivores.
- Decomposers break the dead down and return nutrients to the soil.
- A food web is many food chains linked together.
- Energy is lost as heat at every step, so chains are rarely longer than five.
- Remove one species and everything connected to it is affected.
- Pond: pondweed → tadpole → dragonfly larva → fish → heron.
Habitat is where something lives. Niche is the job it does there. Two different questions.

- Who is the Ecosystems poster for?
- Ecosystems is filed under 5th Grade (ages 10–11), so it matches what that year asks a child to remember. It is equally useful to an older student revisiting science, and to the parent or teacher answering the question at the kitchen table.
- When should you use the Ecosystems poster?
- Map an ecosystem you can visit — a pond, a hedge, even a lawn. A wall chart earns its place by being glanceable from where the work is happening, so Ecosystems belongs on the wall where that science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Ecosystems?
- Body Systems Overview, Circulatory System and Digestive System sit alongside Ecosystems in the 5th Grade set. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Body Systems OverviewCirculatory SystemDigestive System
- Is the Ecosystems poster free to download and print?
- Yes. Ecosystems downloads as a free PDF with no account, no email and no watermark, like everything else in the 5th Grade set. 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 Ecosystems poster print at?
- Ecosystems 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 Ecosystems loses nothing.Printing guide
