Ecosystems depend on abiotic (non-living) factors: water, heat, substrate, light, gas levels like oxygen, atmospheric pressure, and radiation. Each plays a distinct role — water as a solvent and transport medium, heat enabling cellular chemistry, substrate anchoring plant growth, light powering photosynthesis, and gases fueling respiration. Together they form the physical scaffolding without which no biological community could function.
