Chapter 47.2, Problem 2TYK
Summary Introduction
Introduction:
Biological diversity, biodiversity, is the variations in different species and the ecosystems in which these species survive. Biodiversity is studied in three stages, species diversity, genetic diversity, and ecosystem diversity.

It is said that biodiversity facilitates to sustain a sound life, Elaborate the above sentence with the gravity of Biodiversity in every walks of human being.
Biodiversity decline leads to declines in ecosystem and functioning and ecosystem stability. Cite one natural process that can promote the diversity, ecological function and stability of an ecosystem.
The term “ecology” is derived from the Greek meaning “house” or “place to live.” However, as used by scientists, the term “ecology” is not the same as “environment.” How do these terms differ?

- Ecology and Biology: Shannon Diversity Index: Definition & Example The Shannon Diversity Index (sometimes called the Shannon-Wiener Index) is a way to measure the diversity of species in a community. Denoted as H, this index is calculated as: H = -Σpi * ln(pi) where: Σ: A Greek symbol that means “sum” ln: Natural log pi: The proportion of the entire community made up of species i The higher the value of H, the higher the diversity of species in a particular community. The lower the value of H, the lower the diversity. A value of H = 0 indicates a community that only has one species. The Shannon Equitability Index is a way to measure the evenness of species in a community. The term “evenness” simply refers to how similar the abundances of different species are in the community. Denoted as EH, this index is calculated as: EH = H / ln(S) where: H: The Shannon Diversity Index S: The total number of unique species What is the Shannon diversity index value for this community?
