Ecosystems and Food Webs


As a High School or Undergraduate Biological Sciences of Environmental Sciences teacher, you can use this set of computer-based tools to teach about ecosystems, biomes, food chains, and food webs and how the balance of an ecosystem can be disrupted by climate change induced insect outbreak..

Warmer temperatures and altered water availability due to climate change are causing unusual outbreaks of insect populations globally. This lesson plan shows how Bark Beetles (Mountain Pine Beetle, Spruce Beetle) destroy large swathes of forests, thereby disturbing ecosystems globally. Examples discussed in this lesson plan include climate impacts on the ecosystems of the forests of Yellowstone National Park (USA), Bhutan and Central Europe.

Thus, the use of this lesson plan allows you to integrate the teaching of a climate science topic with a core topic in Biological Sciences and Environmental Sciences.

Learning Outcome

The tools in this lesson plan will enable students to:

  1. Describe the structure and function of an ecosystem
  2. Discuss the trophic levels of organisms within an ecosystem
  3. Evaluate biomes and their component food webs
  4. Apply their learning to real-world ecosystem challenges
  5. Describe how Bark Beetles destroy forest ecosystems
  6. Discuss climate change related Bark Beetle outbreaks globally

Teacher contributed lesson plan by Kinley Choden (UWICER), Kinley Dorji (RTC), Bhuwan Kafley (RTC), and Rachana Sharma (Pelkhil School), Bhutan.
