Big Ideas
  • Matter and energy move through ecosystems in predictable ways, and changes in the ecosystem can disrupt these patterns.
  • Changes in one part of an ecosystem can have significant impacts on the cycling of matter and the flow of energy throughout food webs.
Essential Questions
  • How do changes in an ecosystem affect the movement of matter and energy?
  • What happens to a food web when an organism is added or removed from an ecosystem?
  • How are the cycling of matter and the flow of energy related in a food web?
  • How can understanding food webs help us predict the impact of changes in ecosystems?
  • What evidence can be used to support predictions about changes in matter and energy flow in an ecosystem?
