Rainforest Ecosystem Knowledge Assessment

Miss Lisa introduces a social studies lesson on tropical rainforests, emphasizing their importance as they cover only 7% of Earth's surface but house over 50% of plant and animal species. Rainforests are crucial for oxygen production and carbon dioxide absorption. The video explains the rainforest's climate, with temperatures never dropping below 25°C and annual rainfall between 2 to 9 meters. It describes the three layers: canopy, understory, and forest floor, each with unique characteristics. The video highlights threats like logging, mining, and farming, which endanger rainforests and their resources, including potential medicinal plants. The lesson concludes with a call to action to protect these vital ecosystems.
