What is the abundance and variety of species in an ecosystem?
components of species diversity
Species abundance is the number of individuals per species, and relative abundance refers to the evenness of distribution of individuals among species in a community. Two communities may be equally rich in species but differ in relative abundance.
Which ecosystem has an abundance of species but with low species diversity?
An aquarium with many different species of animals, but very few individuals of each species confined to a small space is an example. Likewise, you could have an ecosystem with high abundance, low species richness and therefore, low species diversity. An Oak forest is an example of this.
What are the factors that affect the diversity and abundance of organisms?
A number of evolutionary processes such as selection, gene flow, and historical demography affect the genetic diversity in a population (Hayes and Fox 1991; Boettcher et al. 1995; Bazin et al. 2006). The genetic diversity of individuals within a population affects a range of ecological and evolutionary factors.
How can the abundance and diversity of living organisms in tropical forest be explained?
The biodiversity of these ecosystems can be explained by the great availability of the main abiotic factors for photosynthesis. Since these factors are abundant plants can perform maximum photosynthetic activity living and reproducing easily.
What is genetic species and ecosystem diversity?
Genetic Diversity is the diversity of genetic characteristics (expressed or recessive) within a species (i.e. between individuals and populations of the same species). … Species Diversity is simply the number and relative abundance of species found in a given biological organisation (population, ecosystem, Earth).
