Description

Overview:
This lesson will incorporate how organisms affected at one trophic level in an ecosystem can change the entire structure of the ecosystem. The students will gain an understanding that human impact through deforestation, climate change and even restoration effort can alter an ecosystem's flow of energy through a food web which can have a chain effect spreading through the entire food web. The affect could cause an entire ecosystem to collapse especially if the original organism affected is a keystone species or an umbrella species. Students will learn that the extinction of the polar bears will cause devastation on the Arctic ecosystem that may cause the extinction of world biome.This lesson was developed by Elizabeth Bartlett as part of their completion of the North Carolina Global Educator Digital Badge program. This lesson plan has been vetted at the local and state level for standards alignment, Global Education focus, and content accuracy.
