The correct answer will get Brainliest! Calculate the diversity of the community below using Simpson's diversity index. Provide your answer to the nearest hundredth.
An area of the black forest in Germany contains 134 pitch pines, 24 Douglas firs, and 53 red pines.

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              nn(n-1)

Pitch pine         134       17822

Douglas firs       24552

Red pine            53  2756

Total       N=21121130

So,

D= [211(211-1)] / 21130

D = 2.097

Diversity of the community = 2.097

it has one origin of replication, but it proceeds in two directions - d)

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
