1. An example of one ___________ is a raccoon.2. A group of similar species, like raccoons, is
called a ___________3. A ____________ is used to sample populations in
large ecosystems. 4. What do the different numbers in each mini-
quadrat suggest?5. So why is the quadrat method necessary?
6. You are in charge of studying the Bahia grass in the area between buildings 5 & 6 the grass is dying out suggest what could have happened using the word ‘biotic’ and the word ‘abiotic’.
