The EcoSphere cast
Each friend shows you one idea by how they act. Meet them all and see how the ideas fit together.
-
Chain Food chain / trophic flow (energy moving up levels) -
Niche Ecological role / job-in-the-ecosystem -
Phase Succession / ecosystem change over time (primary, secondary, climax) -
Crown Canopy / trophic-pyramid structure (top vs. base) -
Brink Tipping points / ecosystem thresholds / resilience-or-collapse -
Cinder Carbon cycle — the same carbon moves round and round: air to plant to animal to air -
Lodge Keystone species — one species that holds a whole ecosystem together; remove it and the web unravels -
Mulch Decomposition — what dies doesn't leave; it is broken down and handed back to the living -

Sprawl Invasive species — a species carried somewhere new, where nothing holds it back
