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.
What is biological diversity very short answer?
Biodiversity is all the different kinds of life you’ll find in one area—the variety of animals, plants, fungi, and even microorganisms like bacteria that make up our natural world. Each of these species and organisms work together in ecosystems, like an intricate web, to maintain balance and support life.
What is diversity explain with example?
Diversity is defined as the condition of having many different elements. An example of diversity is a classroom full of children of different backgrounds. noun.
What is class 11 diversity?
“Species diversity is defined as the number of different species present in an ecosystem and relative abundance of each of those species.”
Why is diversity important in biology?
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.
What is the diversity of organisms?
Biodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi.
What are the 3 types biodiversity?
Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms.
What are the 4 types of biodiversity?
Biodiversity is in the form of biological resources, including genes, species, organisms, and ecosystems. Thus, the four main levels of biodiversity are species, genetic, ecosystem, and global biodiversity.
What are 5 reasons why biodiversity is important?
- Biodiversity ensures health and food security. Biodiversity underpins global nutrition and food security.
- Biodiversity helps fight disease. Higher rates of biodiversity have been linked to an increase in human health.
- Biodiversity benefits business.
- Biodiversity provides livelihoods.
- Biodiversity protects us.
What are different types of diversity?
- Cultural diversity. This type of diversity is related to each person’s ethnicity and it’s usually the set of norms we get from the society we were raised in or our family’s values.

What are the three types of species?
Biodiversity is divided into three different types: Genetic biodiversity. Species biodiversity. Ecosystem biodiversity.
Why is genetic diversity important?
Genetic diversity is important because it gives species a better chance of survival. However, genetic diversity can be lost when populations get smaller and isolated, which decreases a species’ ability to adapt and survive.
What causes diversity in organisms?
Several factors contribute to species diversity, including habitat diversity, competition among species, and genetic diversity. Genetic diversity within a species not only is necessary to maintain diversity among species,6 but also contributes to the diversity of food, fiber, and medicines available from nature.
What is an example of biological diversity?
Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can’t even be seen by the naked eye.
Why is diversity important in the environment?
Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations. Even if certain species are affected by pollution, climate change or human activities, the ecosystem as a whole may adapt and survive.
What are the main types of biodiversity?
The three types of biodiversity are: Species Diversity. Genetic Diversity. Ecological Diversity.
What are the 7 components of biodiversity?
- Genetic Diversity. Every species on Earth is related to every other species through genetic connections.
- Species Diversity. Species diversity is the variety of species within a habitat or a region.
- Ecological Diversity.
- Biodiversity Agreements.
- Human Impact.
How do humans affect biodiversity?
The main direct cause of biodiversity loss is land use change (primarily for large-scale food production) which drives an estimated 30% of biodiversity decline globally. Second is overexploitation (overfishing, overhunting and overharvesting) for things like food, medicines and timber which drives around 20%.
What is biodiversity advantages and disadvantages?
This is Expert Verified Answer 2) More plants means the better environment and lesser effect of green house gases or temperature rising. 3) The biodiversity helps to maintain the food web circle , disturbing can result in the scarcity of food.

Primary dimensions of diversity include age, ethnicity and culture, gender, race, religion, sexual orientation, and capabilities (Schwind, Das, & Wagar, 2007). Secondary, diversity includes mainly factors such as socio-economic sta- tus, education, religion, geographical affiliation and marital status (Sweetman, 2004).
What is a good example of diversity?

Diversity also includes characteristics such as professional skills, working style, location, and life experiences.
Are humans species?
The billions of human beings living today all belong to one species: Homo sapiens. As in all species, there is variation among individual human beings, from size and shape to skin tone and eye color.
Which is the largest scale of biodiversity?
Ecological diversity is the largest scale of biodiversity, and within each ecosystem, there is a great deal of both species and genetic diversity.
