Ecological Pyramids & Nutrient Cycles

Today (and yesterday) students took notes on how energy and matter moves through ecological systems. We compared three types of ecological pyramids, food pyramids vs. webs, and started to look at cycles of matter.

Homework: Read and take notes on pages 78-80 for a reading quiz on Friday.

We also watched two video clips (and of course the water cycle song is cheesy, but that's the point!)

The Water Cycle

The Carbon Cycle
