asprin = willow or boswelia
chirps chirps = cricket flower
avani biodegradble carrier bags= casava
sugar = sugar cane

Question 33

how to analyze the total number of organism?

Answer 33

total number of organism = total number in a sample x the total area divided by total sample area

Answer 35

use larger sample size
