Biodiversity is the variety of different forms of life on earth, including the different plants, animals, micro-organisms, the genes they contain and the ecosystem they form. It refers to genetic variation, ecosystem variation, species variation (number of species) within an area, biome or planet.
What is biodiversity meaning and definition?
Biodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi.
What is biodiversity and its 3 types?
Biological diversity, or “biodiversity,” refers to variability found at all levels of biology. Biodiversity is commonly broken down into three levels or types: genetic diversity, species diversity, and ecosystem diversity.
What is biodiversity with example?
Biodiversity is the variety of life. It can be studied on many levels. At the highest level, one can look at all the different species on the entire Earth. On a much smaller scale, one can study biodiversity within a pond ecosystem or a neighborhood park.
The Convention on Biological Diversity defines biodiversity as the variability among living organisms from all sources including, among other things, terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are a part; this includes diversity within species, between species and of
Why is biodiversity important easy definition?
Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat. And people also value nature of itself.
What are the 3 importance of biodiversity?
Benefits to societies from biodiversity include material welfare, security of communities, resilience of local economies and human health. The benefits of biodiversity to humans are sometimes called ‘ecosystem services.
What are the 4 components 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 are the main types of biodiversity?
Types of Biodiversity. Biodiversity includes three main types: diversity within species (genetic diversity), between species (species diversity) and between ecosystems (ecosystem diversity).
What is biodiversity and its causes?
Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change.
Who is the father of biodiversity?
E.O. Wilson
D. He is known as “the father of biodiversity”. E.O. Wilson died on December 26, 2021 in Burlington, Massachusetts, at the age of 92.
What is biodiversity according to Unesco?
biodiversity-688.
Biological diversity, or biodiversity, is manifested at all levels of organization (genes, species, ecosystems and landscapes) and is seen in all forms of life, habitats and ecosystems (tropical forests, oceans and seas, savannah ecosystems, wetlands, drylands, mountains, etc.).
Who discovered biodiversity?
Charles Darwin [2] identified the first principle of the origin of modern biodiversity, namely that all species were linked in a single great phylogeny, or tree of life, and that all could be traced back to a presumed single original species at some distant time in the geological past.
Why is biodiversity important 10 points?
Biodiversity is important to humans for ecological life support, biodiversity gives a functioning ecosystem that provides oxygen, clear air and water, plant pollutions, pest control, wastewater treatment and lots of ecosystem services. Note: Species are found 3 million to 100 million on earth.
What are the 4 importance of biodiversity?
Biodiversity conservation protects plant, animal, microbial and genetic resources for food production, agriculture, and ecosystem functions such as fertilizing the soil, recycling nutrients, regulating pests and disease, controlling erosion, and pollinating crops and trees.

What is the value of biodiversity?
Environmental Benefits
The biggest impact of biodiversity is on the environment. Healthy ecosystems help to maintain the Earth’s natural processes. Soil turnover, water purification, pest control, and other processes wouldn’t be possible without the species that support them.
What are the benefits of biodiversity?
Biodiversity supports human and societal needs, including food and nutrition security, energy, development of medicines and pharmaceuticals and freshwater, which together underpin good health. It also supports economic opportunities, and leisure activities that contribute to overall wellbeing.
What are the 5 factors that affect 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.
