  1. Fantastic Video. So informative and clear. Mr. Anderson, what program did you use to produce this video?


  2. His description of exponential growth is somewhat inaccurate. Instead of the y=2^x pattern that he describes, initial growth of a population follows more of a Fibonacci pattern (1, 1, 2, 3, 5, 8, 13, 21…) or some multiple of that.

  3. "I'm not going to be around, so it's no big deal" In other words, "screw you guys, I'm going to be dead by then, so you millennials can deal with the problems my generation caused." 🙂 Ah, it's nice to have a bright future to look forward to.

  4. According to 4:59min,does it mean the temperature zones have largest diversity?I think the trophic has largest.

  5. You always have a quick way to describe the topic .. That's why I watch those videos as an introduction before studying . Good job !

  6. How about helping me to my report? My topic is Community Function. And i can't find it anywhere.

  7. Wow thank you Mr. Anderson for teaching me so much about biology. You should come to my hometown and teach me more if you know what I mean…
