FAQs on Patterns of Biodiversity
Q. What is biodiversity?
Answer: Biodiversity, simply put, is the variety of life on Earth. This includes all plants, animals, and microorganisms, as well as the ecosystems they inhabit.
Q. What are the main patterns of biodiversity?
Answer: There are three main patterns of biodiversity: species richness, species evenness, and species abundance.
Q. What is species richness?
Answer: Species richness is a measure of the number of different species in an area. The more species there are, the higher the species richness.
Q. What is species evenness?
Answer: Species evenness is a measure of how equal the abundance of different species is. If all species are equally abundant, the evenness is high. If one species is much more abundant than the others, the evenness is low.
Q. What is species abundance?
Answer: Species abundance is a measure of how many individuals of a species there are. A species can be abundant even if there are only a few individuals, as long as those individuals are very common.
