Biodiversity and Its Importance Study Guide


The balance of all the ecosystems around the world is a huge factor in the survival of the human species. The system responsible for this stability is biodiversity! The system is never static-it goes through constant changes, and this evolution is seen in an entire species and each organism. Biodiversity definition

You can always define biodiversity and its importance in terms of how it helps humans survive. Still, the real definition of biodiversity is the variation in animals, plants, and other living creatures from different sources, including ecosystems like marine, terrestrial, and desert. It describes not only the variety of life but also the ecological complexity of different ecosystems. Types of biodiversity

There are three different types of biodiversity, and these include:

Types of biodiversitySource

1. Species biodiversity

The variety of different species present within a region or a habitat is known as species biodiversity, and this is one of the most basic forms of biodiversity. For example, there are about 85000 flowering plant species present in the tropical regions of South and North America.

2. Genetic biodiversity

Genetic biodiversity is the genetic variations within a specific species. Individuals present in the same species still differ with some variations in their genetic information. An example of this is how humans look different from each other though we are all part of the same species.

3. Ecological biodiversity

Ecological biodiversity focuses on the variations in different species of animals and plants present in the same ecosystem and how they are connected through food webs and food chains.

Importance of Biodiversity

Biodiversity is vital for the smooth functioning of ecosystems on earth. It provides

  • Ecological stability: An ecosystem is designed with a balance in place. Disrupting this balance through the lack of diversity will affect life on earth, and reduce our ability to respond to environmental stressors
  • Economic balance: Materials found in each ecosystem provide a basis for most flourishing businesses that aid humans in their daily lives. Diminishing diversity will in turn lead to less resources
  • Ethics: All species on earth have a right to exist. Causing extinction of a species by humans violates the basis of that rule

It is important to note that conservation of our biodiversity is critical to the survival of the human race itself. What would the earth be, without these gifts from nature?


  • With these biodiversity notes, it is clear how it is fundamental for all the living beings on earth.
  • Therefore, it is important to know what biodiversity means and ensure that the changes we make to an ecosystem do not alter the system itself for the worse.
  • A loss in biodiversity will lead to food scarcity, less accessibility to essential resources, increased natural disasters, and more.


1. What is biodiversity and its importance?

The variety of living things from different sources on earth, including the marine, desert, and terrestrial ecosystems, encompassing the ecological, evolutionary, and cultural processes of which they are part is the definition of biodiversity.

Many experts stress the importance of biodiversity because it can help with many natural services like maintaining the stability of the ecosystem, providing resources for manufacturing food and medicines, and reducing the environmental stress humans create.

2. What is biodiversity, and why is it an important essay?

Biodiversity is everywhere around us- we live, breathe, and exist, reaping its benefits, making it a very important system for us to protect. Here is a short note on biodiversity and everything you need to know about it:

3. What do you mean by biodiversity?

Biodiversity is the variety, and the number of animals, plants, and other living organisms that exist and are a part of an ecosystem. The measure of the variety of living organisms that live in different sources like marine, terrestrial and desert ecosystems is the definition of biodiversity.

The meaning of “bio” is “life” while “diversity” means “variety,” and the fundamental unit with which we measure it is “species.

4. What is biodiversity, and why is it so important for our environment?

Biodiversity describes the variety and richness of all living creatures on earth, and life would not sustain without it. This variation in living beings allows us to deal with these differences responsibly and know how to protect and support them.

Biodiversity is very important because it gives us a reliable ecosystem that provides humans with clean water and air, oxygen, pest control, plant pollution, wastewater treatment, and more. Still, this significance of biodiversity is often not used responsibly by humans.

5. What are 5 benefits of biodiversity?

Variation of living beings on earth is biodiversity, importance, and benefits of it being:

  • It ensures food and health security
  • It helps humans fight various diseases
  • Biodiversity-importance in businesses
  • It provides livelihoods
  • It protects us by keeping earth habitable

6. Why is biodiversity important to human biodiversity?

While biodiversity is important to protect all the species on earth, what is the importance of biodiversity to humans? It plays an important role in nutrition for humans because it influences the world’s food production. Biodiversity enhances and stabilizes the productivity and fertility of the soil, providing all harvested livestock, crops, and marine species with enough genetic resources.

7. How biodiversity is important for humans?

One of the most important benefits of biodiversity for humans is its foundation for human health. Biodiversity provides us with life-sustaining services and goods that the sustainable use of biodiversity and its conservation can ensure humans remain healthy.

8. What is biodiversity in your own words?

Biodiversity is the number and variety of living organisms present in different ecosystems and their relative frequencies and organization in the system. It has many economic and ecological significances, and it provides all living beings with nutritious food, resources, health, and many more.

9. What is the importance of biodiversity in a natural ecosystem?

Biodiversity is everywhere- in water and on land and its benefits on the natural ecosystem will improve the lives of all living creatures on earth. Biodiversity is important in natural ecosystems because of its impact on various natural processes like water cycling and nutrient cycling, plant pollination, soil formation and retention, climate regulation, pollution, resistance to invasive species, and more.

10. What is the importance of biodiversity for development?

A short note on biodiversity- it is the variety of living species present on earth and the way they are classified into different levels of biodiversity. Biodiversity helps in sustainable development by providing resources and provisions for water, fiber, and food. It also supports health and provides jobs in fisheries, agriculture, forestry, and other nature-related sectors.
