Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.
Which ecosystem has highest species diversity?
Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest.
What is the highest diversity index?
The maximum value of the index is LOG(k). This value occurs when each group has the same frequency (i.e., maximum eveness). This normalizes the Shannon diversity index to a value between 0 and 1. Note that lower values indicate more diversity while higher values indicate less diversity.

How can you tell if an ecosystem has high biodiversity?
When an ecosystem has high biodiversity it is always more stable than an ecosystem that has low biodiversity. … Low biodiversity is when there are a few prominent species and a low number of other species within the habitat. High biodiversity is a habitat or ecosystem that has a high number of different species.
What is Simpsons Diversity Index?
Simpson’s Diversity Index is a measure of diversity which takes into account the number of species present, as well as the relative abundance of each species. As species richness and evenness increase, so diversity increases. n = the total number of organisms of a particular species.
Which of the following is Diversity Index?
A diversity index is a quantitative measure that reflects how many different types (such as species) there are in a dataset (a community), and that can simultaneously take into account the phylogenetic relations among the individuals distributed among those types, such as richness, divergence or evenness.
Which garden has the highest Shannon index?
The highest Shannon diversity index of butterfly communities was at the grassland followed by the natural forest, while the lowest diversity index was at the artificial forest habitat. The species richness index of butterfly communities was the highest at the grassland and the least at the artificial forest.
Which of the following country has highest biodiversity?
Brazil is the only country with highest biodiversity. Biodiversity accounts one-tenth of the world’s overall species.
What Forest has the most biodiversity?
Tropical rain forests are some of the most biologically diverse ecosystems on the planet.
What does it mean if a place has high biodiversity?
Biodiversity refers to the variety of life. When biodiversity is high, it means there are many different types of organisms and species. … And every organism plays a unique role and contributes to how coral reef communities survive and function.
