What are 3 types of biodiversity?
Biodiversity is usually explored at three levels – genetic diversity, species diversity and ecosystem diversity. These three levels work together to create the complexity of life on Earth.
What are the 4 types of biodiversity quizlet?
The four major components of biological diversity are: Functional Diversity (biological or chemical processes such as energy flow and matter recycling needed for the survival of species, communities, and ecosystems), Ecological Diversity (the variety of terrestrial and aquatic ecosystems found in an area or on the …
What are 3 causes of biodiversity?
Why is biodiversity important?
- Changes in land use (e.g. deforestation, intensive mono-culture, urbanisation)
- Direct exploitation such as hunting and over-fishing.
- Climate change.
- Invasive alien species.
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.
How many types of biodiversity conservation are there?
Conservation can broadly be divided into two types: In-situ: Conservation of habitats, species and ecosystems where they naturally occur. This is in-situ conservation and the natural processes and interaction are conserved as well as the elements of biodiversity.
What is functional diversity quizlet?
functional diversity. the variety of processes such as energy flow and matter cycling that occur within ecosystems as species interact with one another in food chains and webs.
What is the examples of biodiversity?
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 the four major components of biodiversity biological diversity )?
The four major components of biodiversity are species diversity, ecological diversity, genetic diversity, and functional diversity.
What is biodiversity explain the three levels of biodiversity?
Biodiversity includes all organisms, species, and populations; the genetic variation among these; and all their complex assemblages of communities and ecosystems. Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity.
What are the three pressures that lead to biodiversity?
Three major interacting drivers affecting all these pressures have been (and will be) climate, human population growth and the demands placed on the environment to support human lifestyles. It will be important to address all three of these drivers if pressures on biodiversity are to be reduced to desirable levels.
What causes biodiversity?
The various factors that influence biodiversity include -temperature, altitude, precipitation, soils, and their relation with other species. For instance, ocean biodiversity is 25 times lesser than terrestrial diversity. Biodiversity also increases its form as it moves from the poles towards the tropics.
