biodiversity / ( ˌbaɪəʊdaɪˈvɜːsɪtɪ) / noun the existence of a wide variety of plant and animal species in their natural environments, which is the aim of conservationists concerned about the indiscriminate destruction of rainforests and other habitats


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. However, only around 1.2 million species have been identified and described so far, most of which are insects.

Biodiversity is a term which describes every living organism within a single ecosystem or habitat, including numbers and diversity of species and all environmental aspects such as temperature, oxygen and carbon dioxide levels and climate. Biodiversity can be measured globally or in smaller settings, such as ponds. Why is Biodiversity Important?

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.

Biodiversity = Variety of Life A small, brown pika hides among rocks. JR Douglass, NPS Photo. Biological diversity (or biodiversity) is the variety of life on Earth. It includes all living things, not just the plants and animals that are common or easily seen. It includes species that are not well known, such as microorganisms or invertebrates.

Biodiversity describes the richness and variety of life on earth. It is the most complex and important feature of our planet. Without biodiversity, life would not sustain. The term biodiversity was coined in 1985. It is important in natural as well as artificial ecosystems. It deals with nature's variety, the biosphere.

WHAT IS BIODIVERSITY? Biodiversity is the sum of all life on earth. Every single individual lifeform from the smallest bacteria in the soil to the largest whale in the sea, is a component of Earth's biodiversity. But biodiversity doesn't stop at the individual. Biodiversity is also the relationships between these lifeforms and their habitat.

The Convention on Biological Diversity similarly defines biodiversity as the "variability among living organisms from all sources''. Those definitions are so broad that they can be clearly understood only by considering particular levels of biological organization—genes, species, communities, ecosystems, and even our planet.

Biodiversity is all the living things on our planet - from the smallest bacteria to the largest plants and animals. So far, we have identified around 1.6 million species but that is probably only a small fraction of the forms of life on Earth. Biodiversity on Earth is the result of four billion years of evolution.

bi·o·di·ver·si·ty (bī′ō-dĭ-vûr′sĭ-tē) n. 1. The number and variety of species found within a specified geographic region. 2. The variability among living organisms on the earth, including the variability within and between species and within and between ecosystems. American Heritage® Dictionary of the English Language, Fifth Edition.


1. Biodiversity is the Rich Variety of Life on Earth There are three main levels of biodiversity : Variety of Genes Poodles, beagles, and rottweilers are all dogs. But they're not the same, because their genes are different. The difference in our genes makes us all different. Variety of Species Scientists group living things into distinct species.

Biodiversity—short for biological diversity—is the variety of all living things and their interactions. Biodiversity changes over time as extinction occurs and new species evolve. Scientists often speak of three levels of diversity: species, genetic, and ecosystem diversity. In fact, these levels cannot be separated.


Biodiversity is fundamental to both planet and people. It provides us with clean air and water, food and medicines. But biodiversity is in crisis. Only 23% of species and 16% of habitats under the EU Nature Directives are in good health.

Concept of Biodiversity. Different types of genes, gene pools, species, habitats, and ecosystems in a particular place and various parts of the earth are called biodiversity. Currently, the total described species of all plants and animals is slightly more than 1.5 million. Robert May estimated global species diversity at about 7 million.

Simply put, biodiversity refers to the incredibly rich variety of life on Earth. The word itself is a contraction of "biological diversity" and refers to every living thing on the planet. It...


Biodiversity is not limited to national parks: it is everywhere.... is integral to sustainable development. by providing vital goods and services, such as food, timber, carbon sequestration and flood regulation. Key messages. Biodiversity is the biological diversity between species, within species and between ecosystems.

Levels of Biodiversity. Biodiversity is wide-ranging and is normally divided into three types or levels: Genetic Diversity. Species Diversity. Ecological Diversity. Let's have a detailed look at them: 1. Genetic Diversity. All species on Earth are somewhat related through genetic connections.

Biodiversity Definition. Biological diversity largely describes the change of life from genes to ecosystems, comprising their existences, genetic variations, their environment, populations and the ecosystem in which they are existing and other evolutionary developments that keep the system functioning, changing and adapting.

Why is biodiversity important? 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.

Upcoming biodiversity topics to cover. This is a growing collection of resources and research on biodiversity. Biodiversity aspects we have not yet covered but aim to in the near future include: Insect populations. Impacts of climate change on biodiversity. Expansion of our work on bird species. Expansion of our work on fish and overfishing.

Here are three considerations that businesses can be mindful of when thinking about biodiversity: 1. Understand the value chain and nature-related dependencies within it. Companies' first step should be to identify where their highest dependencies on nature lie across their supply chain. Adopting a risk management framework, such as that ...

Introduction. Biodiversity is a common enough word that almost every one of us has heard it before. We know it concerns the many forms of life on Earth, existing in many parts of the world, especially the recent events and concerns of the pandemic, ensuring adequate food and water, promoting sustainable development.


Biodiversity is the amazing variety of life on Earth. It encompasses diversity on many levels; the vast number of species of plants and animals, the genetic diversity within and between these species and the different biomes and ecosystems of which they are part, including rainforest, tundra and desert. Biodiversity also includes the diversity ...
