jl777 asked:


I was reading my ecology book and there was one part that i didnt understand. English is not my first language so its really hard for me to understand. Can anyone explain to me more easier?

“The recognition that the form and function of plants within a region reflected the constraints imposed by the physical environment led the way for a new generation of scientists that explored the relationship between plant biology and plant geography.”

Thanks!

JuicyGirl asked:


I’m doing a project in a Human Geography course I am taking and wanted more clarification from those who are more familiar with the term. Please, no “Folk group’s close relationship with the physical environment,” just examples and a better description.

Thanks!
