Ecosystem Relationships and Functions

The video tutorial explores various relationships within ecosystems, focusing on producers, consumers, and decomposers. It explains how producers like plants convert solar energy into chemical energy through photosynthesis, which is then transferred through food chains involving consumers. Decomposers play a crucial role in recycling nutrients back into the soil. The tutorial also covers predator-prey dynamics and different symbiotic relationships, such as mutualism and parasitism, highlighting the complexity and interdependence of ecosystem interactions.
