Biodiversity refers to the whole ecosystem of living organisms and the diversity within them. Biodiversity refers to the variation among the species, within the species and within an ecosystem.

Walter G. Rosen coined the term “biodiversity” in 1986.

Biodiversity has both ecological and economic value. It provides food, fuel, clothing and other resources. It also provides monetary benefits through tourism. For a sustainable lifestyle, it is important to be well-versed in biodiversity.

Biodiversity: Importance

Biodiversity plays an important role in maintaining an ecosystem’s ecological balance. It refers to the diversity of species found in a specific region. Every species has an important role to play in biodiversity.

Biodiversity and its ecological role

Each species of biodiversity serves a vital role in the ecosystem. They play a significant role in the production, decomposition, fixation and regulation of water and nutrients within the ecosystem. The ecosystem’s stability is enhanced by the diversity of its species.

Economical role of Biodiversity

Biodiversity can be used as an energy source and is essential for the production of raw materials such as oil, lubricants or perfumes.

For thousands of years, it has been recognized that plant species are important for many medicinal uses. According to some reports, over 70% of anticancer drugs are derived from plants found in tropical rainforests.

Scientific Role of Biodiversity

Each species in the ecosystem provides enough evidence to show how life evolved and what role each species plays in maintaining sustainability.

Classification of Biodiversity

Three main types of biodiversity are possible:

• Genetic Diversity (Diversity within species)
• Species Diversity (Diversity within species)
• Ecosystem Diversity (Diversity among ecosystems)

Genetic Diversity

The genetic makeup of each individual in a particular species is different. Genetic diversity is the result of genetic variability between members of different species. Two individuals who are closely related have more genetic information. They are thus more similar.

Species Diversity

A species’ diversity is the number of species in a specific area or habitat. This type of diversity is present in both the agricultural and natural ecosystems.

The United States has over 85,000 flowering plant varieties. In South America, tropical North America has more than 50,000, and tropical and subtropical Asia has more than 50,000. However, only 35,000 of the flowering plant species are found in subtropical Africa. Europe is home to around 11,300 of these vascular plants. There are also fewer species in other areas like the salt flats and polluted rivers.

Ecosystem Diversity

There are many different ecosystems, each with its own unique species. These ecosystems are different because of the diversity in their habitats. This ecosystem diversity can only be found in one region, country or state. This kind of diversity also includes forests and grasslands as well as deserts and mountains.

What is the Need for Classification of Organisms?

The need for classification can be described for the following reasons as seen below:

We can better understand diversity through classification

• It aids in the identification and understanding of living organisms
• Biodiversity and classification of microorganisms help us learn about the different types of animals and plants, their characteristics, similarities, and differences
• This allows us to see how complex organisms evolved from simpler ones
• They are divided into different categories to help you understand the similarities and differences among different living organisms
• The classification tool allows us to manage a wide variety of living forms
• Understanding the interrelationships between different groups of organisms is crucial
• The basis for other biological sciences is the classification

Loss of Biodiversity

The loss of biodiversity is the reduction in the number or abundance of a species in a habitat. This can lead to the loss of biodiversity, which can either be reversible (or permanent).

Human activities are the main reason for biodiversity’s decline. These sudden climate changes pose a major threat to biodiversity. A growing population has resulted in a greater demand for natural resources and a higher level of waste generation.

The Causes of Loss of Natural Biodiversity

Here are some major causes of biodiversity decline:

• The ecological balance is maintained by the natural habitat. Many trees are being cut every year to build industries, highways, settlements, and other infrastructures that meet human needs. This makes the species vulnerable to predation, and ultimately leads to its death
• It has been a significant factor in the decline of biodiversity that wild animals have been hunted for their meat. More than 90 rhinos have been killed by poachers since 2013. According to records, 9 Indian rhinos were killed in Kaziranga National Park in Assam
• Exercising medicinal plants for various laboratory purposes has led to the extinction of these species. Many animals are also killed for research purposes in medicine and science
• Nature’s calamities, such as earthquakes, floods, and forest fires, can also cause the loss of biodiversity
• Air pollution plays a significant role in biodiversity loss. Rapid tree felling has led to an increase in carbon dioxide levels in the atmosphere, which can lead to climate change. The result has been an increase in the ocean and land temperatures, which has adverse effects on species
