Question

Species diversity is maximum in
A. Tropical rainforest
B. Temperate forest
C. Deserts
D. Hillslopes

Answer 1

Hint: The diversity of species is more complicated and requires a measure of the number of species in a population and a measure of each species' abundance. An index, such as Shannon's Index H ', typically defines species diversity.

Complete answer:
An ecosystem situated near the equator is the tropical rainforest. It has the greatest biodiversity, both in flora and fauna and in bacteria, of all the earth's ecosystems. The optimum growing conditions in equatorial locations are responsible for this high diversity. Tropical rainforest, pronounced tropical rain forest, luxuriant forest found in the Equator's wet tropical uplands and lowland tropical rainforest, heavy rainforest, luxuriant forest in the tropical and lowland wetlands of Equator. Tropical rain forests are dominated by widely-paved trees that are a thick upper canopy (leafy layer), which contain a range of plants, and other living environments that make up one of the biggest ecosystems in the world (major living areas).
In both the Northern and Southern Hemisphere, temperate forests are those located in the mild climates between the tropics and boreal regions. They can also be called ``four-season forests" since four distinct seasons appear to occur in the midlatitude climates that harbor them.
With the fewest plant and animal species in the driest deserts, the diversity of desert species is very much dependent on rainfall and vegetative cover. The Sonoran Desert, with a significant variety of distinct plant associations, is exceptionally rich in plants.

Hence, the correct answer is option A-Tropical rainforest.

Note:
In an ecological community, ecosystem, or area, species richness is the range of different species represented. The species' diversity is simply the number of species, and the species' abundances or their relative distribution of abundance are not taken into account.
