Ecosystem Elements in Your Backyard: Biotic and Abiotic Discoveries

The video explores ecosystems, highlighting the distinction between biotic (living) and abiotic (non-living) factors. It explains the characteristics of living organisms, using trees as an example, and contrasts them with non-living entities like rocks and clouds. The video provides guidelines for identifying these factors and emphasizes the interdependence of living and non-living components in ecosystems.
