Biology Ch15 Communities Flashcards
Within a community each species is independent when it comes to food, shelter and pollination.(True or False)
False, within any community of living organisms each species is not independent of the others. They rely on each other for resources.
What is the term for the non-living parts of a community?

Decrease
If species A is better at competing for a resource than species B, will the numbers of species A increase or decrease?
