Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can’t even be seen by the naked eye.
What are 3 biodiversity examples?
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity.
What is diversity within species?
Diversity within species is the result of continuous processes of variation generation and subsequent selection and drift (Fig. 1). Mutations and gene flow introduce genetic variability into otherwise identical lineages of clonal daughter cells.
What is the best example of species diversity?
Australia’s Great Barrier Reef is an example of species diversity. It is the home to the largest coral reef in the world. It contains approximately 400 different types of coral species, 150 fish species, 4000 species of mollusks, and 10 species of turtles.
Which species are included under biodiversity?
Biodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi.
What are the 4 types of biodiversity?
Four Types of Biodiversity
- Species Diversity. Every ecosystem contains a unique collection of species, all interacting with each other. …
- Genetic Diversity. Genetic diversity describes how closely related the members of one species are in a given ecosystem. …
- Ecosystem Diversity. …
- Functional Diversity.
What is an example of ecosystem?
Examples of ecosystems are: agroecosystem, aquatic ecosystem, coral reef, desert, forest, human ecosystem, littoral zone, marine ecosystem, prairie, rainforest, savanna, steppe, taiga, tundra, urban ecosystem and others.
What is diversity and biodiversity?
The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.
What is an example of ecosystem diversity?
An example of ecological diversity on a global scale would be the variation in ecosystems, such as deserts, forests, grasslands, wetlands and oceans. Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity.
What is a example of a species?
Humans ( Homo sapiens ), moose ( Alces laces ), black bears ( Ursus americans ), jack pines ( Pinus banksiana ) are all examples of different species.
What is animal biodiversity?
Biodiversity is all the different kinds of life you’ll find in one area—the variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural world. Each of these species and organisms work together in ecosystems, like an intricate web, to maintain balance and support life.
What are some examples of genetic diversity and species diversity in that environment?
Examples of Genetic Diversity
Different plant breeds are crossbred to get the desired trait in a particular plant. Humans have created dog breeds by selective breeding. Coyotes are naturally evolved generalist species adaptive to an array of environments.
How many animal species are there?
The natural world contains about 8.7 million species, according to a new estimate described by scientists as the most accurate ever. But the vast majority have not been identified – and cataloguing them all could take more than 1,000 years.
Which of the following is an example of ecological use of biodiversity?
Eco-tourism is an example of non-consumptive use of biodiversity, whereby the aesthetic of biodiversity (such as forests) are exploited for economic gains. Are there any other examples and research done on this?
What are some examples of low biodiversity ecosystems?
Example of ecosystem with low biodiversity is definitely a desert. Then there are cold deserts in Antarctica and Gobi basin of central Asia, where biodiversity is minimum. Example of ecosystem with high biodiversity is tropical rain forest as seen in Amazon basin of south America.
