Options:
A) P diversity
B) y diversity (gamma)
C) Landscape diversity
D) Ecosystem diversity
Show Answer
Answer:
Correct Answer: B
Solution:
Alpha diversity is the diversity of species in a given community or habitat. Species richness and evenness or equability is the basis of alpha diversity.
In beta diversity, variability occurs in the communities due to replacement of species with the change in communities or habitat. Many microhabitats, niches, are present due to which habitat of the organisms change according to their need. Difference in their environmental condition is observed.
Gamma diversity represents the diversity in habitats or ecosystems over a total landscape or geographical area. It includes both alpha and beta diversity.
Biodiversity increases from high to low altitudes that means from poles to equator. The main basis of diversity of an ecosystem is dependent on physical characteristics of the environment, diversity of species and interaction between them.
From the above information we can say that the diversity of an ecosystem of total geographical area is called gamma diversity.
