The two factors contributing to the diversity of species?
The two main factors contributing to the diversity of species are evolution and environmental conditions. Evolution leads to the development of new species over time through processes such as natural selection and genetic variation. Environmental conditions, such as climate, geography, and habitat diversity, play a crucial role in shaping the distribution and adaptation of species.
Why does extinction endanger diversity?
Extinction is the permanent removal of a species which decreases bio-diversity. Bio-diversity is measured in two fashions # of species and # of members/species these two factors together make up a regions bio diversity, therefore with the removal of a species the regions bio-diversity decreases.
What are the two factors that account for diversity of species?
The diversity of sexually reproducing species is a result of the fact that a) gene pools change over time (by selection and genetic drift) and that b) reproductive isolation occurs, leading to the inability of the descendants of formerly interbreeding subpopulations to interbreed (speciation).
What account for the diversity of millions of species on earth?
The diversity of millions of species on Earth is mainly due to evolution through natural selection, where genetic variations within populations lead to different adaptations to specific environments over time, resulting in the emergence of new species. Additionally, factors such as geographic isolation, environmental changes, and ecological interactions also contribute to the diversification of species.
The measure that relates the number of species in a community to the relative abundance of each species is called?
The measure that relates the number of species in a community to the relative abundance of each species is called species diversity. It takes into account both the variety of species present and how evenly distributed they are within the community.
What is meant by lower species diversity?
Lower species diversity refers to an ecosystem that has a smaller variety of different species present. This can be due to factors such as habitat destruction, pollution, or invasive species, leading to a decrease in the number and types of organisms that can exist in that environment. Lower species diversity can impact the overall health and stability of the ecosystem.
A term that describes the number and variety of species that live in an area?
Biodiversity refers to the number and variety of species that live in a specific area. It encompasses not only the diversity of species, but also genetic diversity within each species and the variety of ecosystems present.
What factors affect biodiversity?
Ecosystem, genetic and cultural diversity, and the connections between these and all species.
What are factors affecting biodiversity?
There are negative and positive factors affecting biodiversity. The major negative factor is habitat loss and pollution. Some positive factors include restoration and protection of unique habitats, reduced pollution levels by the development of advanced chemistry technologies and better waste disposal processes and the natural changing of regional and global climate conditions.
What factors have caused an increase in invasive introduced species and losses in global diversity?
Factors contributing to the increase in invasive introduced species and losses in global diversity include habitat destruction, climate change, globalization of trade and transportation, and unintentional introductions from human activities. These factors create opportunities for non-native species to establish and outcompete native species, leading to biodiversity loss and ecosystem disruptions.
How is genetic diversity different from species diversity?
The main difference between genetic diversity and species diversity is that genetic diversity is the differences of DNA among individuals of a particular species whereas species diversity is the variety of species in a particular region. Ecological diversity is the variety of ecosystems in a particular area.Oct 30, 2017
