Exploring Biotic and Abiotic Interactions in 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 these factors. The video highlights the interaction between biotic and abiotic factors, emphasizing their impact on ecosystems. It concludes by encouraging viewers to identify these factors in their surroundings.
