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’.
