2.6 Interactions in Ecosystems
... Any change in an ecosystem can affect a food web. These changes can be natural increasing competition for food amongst other organisms. Human actions are one factor that may disrupt an ecosystem and its food web. If an organism in a lower trophic level decreases or is lost, it will affect organism f ...

They have the most energy. • A you move up the pyramid, each level becomes smaller. • Only about 10% of the energy available at each feeding level is transferred to the next level. • A ...

Principles of Ecology
