This music video teaches about food chains and the pyramid of energy. Watch it a few times and you'll be completely on top of trophic levels and energy transfer. This video is a great learning tool for late elementary and middle school age students ...to help build background knowledge and to help make real world connections between nature and the classroom. This video will help students to remember all the details that make food chains what they are. (02:46)

Hank brings us to the next level of ecological study with ecosystem ecology, which looks at how energy, nutrients, and materials are getting shuffled around within an ecosystem (a collection of living and nonliving things interacting in a specific pl...ace), and which basically comes down to who is eating who.

Aquatic Insects
From pbslearningmedia.org, produced by Kentucky Educational Television

In this brief video, a biologist talks about the macroinvertebrates (typically aquatic insects) that form the basis of food webs in healthy streams. In Kentucky, these macroinvertebrates include mayflies, stoneflies, and caddis flies, all of which la...y eggs and spend the early stages of their development in the water. Macroinvertebrates provide food for minnows and other small fish, which in turn become food for larger fish. In streams affected by acid mine drainage, these essential members of the food web are absent, with catastrophic results for the ecosystem. (01:36)
