Ecology on Khan Academy: Why are polar bears only found in the Arctic? Why is mold growing in your shower and not (hopefully) in your sock drawer? Learn how ecologists study the interactions between organisms and their environments, and how these interactions affect where and in what quantity different types of organisms are found.
