Ecosystems and Environmental Impact

The video lesson covers the topic of ecosystems, focusing on Whitten Park. It begins with an introduction to the lesson objectives and a recap of previous lessons. The location and climate of Whitten Park are discussed, followed by an exploration of its ecosystems, including deciduous woodland and water bodies. The nutrient cycle is explained, highlighting its importance in ecosystem balance. The lesson then examines how changes, both human and natural, can disrupt ecosystems, using the introduction of a fish species as an example. The lesson concludes with homework instructions and a quiz.
