It’s time for another installment in the Ecosystem Ed. series! In each of these posts, I focus on a different type of ecosystem around the world and break it down to the basics: what, where, why, how, and who, along with some fun facts. This week, we’re focusing on the DEEP OCEAN, one of Earth’s least-understood and inaccessible ecosystems. (Heads up – this post is kind of a long one. I’m just really excited about the deep sea, okay?)
