Document Summary

Chapter 1: the web of life: the scientific study of interactions between organisms and their environment, the scientific study of interactions that determine the distribution (geographic location) and abundance of organisms, mechanisms of why. Some trees in the rainforest almost exactly the same) if one species is removed it does not change the function of the ecosystem. & we know they will stop growing: we understand the mechanisms that control the pop growth, finite energy and resources result in tradeoffs, organisms have diff strategies ex. Avoid being eaten --physical defenses (spines) or behavioral adaptations: tradeoff b/c when you invest energy & resources invested into any strategy, you take that energy away from somewhere else, ie. Landscapes = collections of ecosystems: areas with substantial differences, typically including multiple ecosystems, biosphere: all the world"s ecosytems, living organisms on earth, plus the environments they live in, super ecosystem .
