Hello! I got the answer! So if you look at the word homo and hetero. Homo means the same and hetero means different. So homology is the study of to show the simliarity between organisms. And heterology is the study of to show difference between organisms. This is my first time answering! Anyways have a good day/night!!

Answer:
Diversity of the community = 2.097
Explanation:
Given:
Number of pitch pines = 134
Number of douglas firs = 24
Number of red pines = 53
Find:
Diversity of the community
Computation:
Simpson's diversity index = N(N-1)/Σn(n-1)
Particular              n	n(n-1)
Pitch pine         134       17822
Douglas firs       24	552
Red pine            53  2756
Total       N=211	21130
So,
D= [211(211-1)] / 21130
D = 2.097
Diversity of the community = 2.097
