Exploring Biotic and Abiotic Factors

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 concludes by emphasizing the interaction between these factors in creating complex ecosystems.
