The law of tolerance
The law of the minimum
Carrying capacity
Biotic potential (because birds lay eggs?)

slash-and-burn
clear-cutting
selective cutting

How are you feeling about these topics? Check off the very nerdy topic-relevant choice that best fits your preparedness. I figured out how to make this NOT for points this time :)
I'm feeling as awesome as a plant sitting in the sun with nutrient-filled soil and tons of water. I got this!!!
I'm feeling like an animal with almost all the resources I need but one or two limiting factors might be the difference between thriving and just surviving. I should review a bit.
I'm feeling like the life expectancy of a mouse ... kind of OK but not really that great. I should probably study.
I'm feeling like the Amazon on fire ... helpppppp me!!!! Time to study!
