What are the three levels of biodiversity quizlet?
All levels of biodiversity are interconnected but there are three levels at which biodiversity is broken down and studied: genetic diversity species diversity and ecosystem diversity. Most research and scientific studies are done at the species level because it is the most clear-cut and easiest to understand.

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.

Biodiversity loss is caused by five primary drivers: habitat loss invasive species overexploitation (extreme hunting and fishing pressure) pollution climate change associated with global warming. In each case human beings and their activities play direct roles.
What are the different levels of biodiversity class 11?
Biodiversity can be discussed at three levels : (i) Genetic diversity (ii) Species diversity (iii) Ecosystem diversity. This refers to the variety of species. It relates to the number of species in a defined area. The diversity of species can be measured through its richness abundance and types.

Species Identity Functional traits and Resource-Use
Species diversity has two primary components: species richness (the number of species in a local community) and species composition (the identity of the species present in a community).
What are examples of biodiversity?
The definition of biodiversity refers to the amount of diversity between different plants animals and other species in a given habitat at a particular time. The different varieties and types of animals and plants that live in the ocean is an example of biodiversity.

What is functional biodiversity?
Functional biodiversity refers to the set of species that contribute to ecosystem services in an agroecosystem. In other words it is the biodiversity that is useful to farmers. It provides benefits that can be valued by the farmer through environmental management.

What are the main approaches of conservation of biodiversity?
Over the past century a wide range of different conservation-oriented approaches have been enacted from local and regional scale activities such as protected area establishment ex-situ conservation recovery planning for species and ecosystems specific threat management (e.g. disease fire) and biodiversity off- …
What is the main objective of conservation of biodiversity?
Biodiversity conservation has three main objectives: To preserve the diversity of species. Sustainable utilization of species and ecosystem. To maintain life-supporting systems and essential ecological processes.
What is the main threat to biodiversity?
Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species climate change nutrient loading and pollution habitat change and overexploitation.
What are the main factors in ecosystem diversity?
Broadly speaking the diversity of an ecosystem is dependent on the physical characteristics of the environment the diversity of species present and the interactions that the species have with each other and with the environment.
How many types of species are there in an ecosystem?
It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing including plants bacteria animals and humans. Scientists have estimated that there are around 8.7 million species of plants and animals in existence.
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.
