Biotic And Abiotic Factors Shaping Ecosystems

The video explores ecosystems, focusing on biotic and abiotic factors. Biotic factors are living elements, characterized by seven traits, while abiotic factors are non-living components like water and sunlight. Examples of ecosystems, such as houseplants and rainforests, illustrate the interaction between these factors. The video emphasizes the importance of these interactions, showing how changes in abiotic factors can significantly impact ecosystems. It concludes by encouraging viewers to identify these factors in their surroundings.
