Ecosystem Interdependence and Effects

The video tutorial introduces the concept of interdependence in ecosystems, focusing on how organisms and abiotic factors rely on each other. Through guided instruction and examples, students learn to identify interdependent relationships within a food web. The lesson discusses energy flow and the impact of changes in ecosystems on populations. Students are encouraged to engage with activities and quizzes to reinforce their understanding.

What does the term 'interdependence' mean in the context of ecosystems?

• The ability of organisms to live independently

• The reliance of organisms on each other for survival
