Hank introduces us to ecology - the study of the rules of engagement for all of us earthlings - which seeks to explain why the world looks and acts the way it does. The world is crammed with things, both animate and not, that have been interacting with each other all the time, every day, since life on this planet began, and these interactions depend mostly on just two things... Learn what they are as Crash Course Biology takes its final voyage outside the body and into the entire world. Can't wait to learn more about ecology? Good news! Crash Course Ecology has 12 episodes you can watch right here: https://www.youtube.com/watch?v=P3wP8v84uqs&list=PL8dPuuaLjXtNdTKZkV_GiIYXpV9w4WxbX Table of Contents 1) Ecological Hierarchy 02:01:2 a) Population 02:12 b) Community 02:26:1 c) Ecosystem 02:50 d) Biome 03:22:1 e) Biosphere 03:51 2) Key Ecological Factors 04:07 a) Temperature 05:06:1 b) Water 05:37 3) Biome Type 06:03:1 Crash Course is on Patreon!

Death is what fungi are all about. By feasting on the deceased remains of almost all organisms on the planet, converting the organic matter back into soil from which new life will spring, they perform perhaps the most vital function in the global food web. Fungi, which thrive on death, make all life possible.
