Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.
What are the major roles of biodiversity in society?
Biodiversity plays an important role in ecosystem functions that provide supporting, provisioning, regulating, and cultural services. These services are essential for human well-being.
What are the roles played by biodiversity?
Species capture and store energy, produce and decompose organic materials, help to cycle water and nutrients throughout the ecosystem, fix atmospheric gases and help regulate the climate. These functions are important for ecosystem function and human survival.
What is biodiversity and how does it play a role in an ecosystem?
Biodiversity is a measure of variation at genetic, species and ecosystem levels. It helps to boost the ecosystem and its productivity where every species have a meaning and a role no matter how small. For example, a large number of plant species mean a great variety of crops.
What role does biodiversity play in the sustainability of an ecosystem?
The higher biodiversity in an ecosystem means that there is a greater variety of genes and species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out natural processes in the face of external stress. Thus, the ecosystem is more sustainable.
What is the role of biodiversity and why should it be preserved?
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.
Why is biodiversity important to ecosystems quizlet?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

What are the major factors that are responsible for the loss of biodiversity What are the steps are needed to prevent them?
The numerous factors are responsible for the loss of Biodiversity (Figure 1) such as pollution, habitat loss, hunting, introduction of invasive species, overexploitation of preferred species, climate change, and natural disasters.
What are the major factors that are responsible for the loss of biodiversity what steps are needed to prevent them class 11th?
The following steps are needed to prevent them:
- Efforts should be made to preserve the species.
- Proper planning and management should be undertaken to stop extinction of species.
- Check on overexploitation.
- Hunting must be restricted.
- International trade in wild animals should be regulated.
What is biodiversity Why is biodiversity important for human lives Ncert?
Biodiversity refers to diverse flora and fauna that exist in a given area. Plants, animals and human beings are interdependent. It is necessary for human beings as we get fresh air, water, food, etc., from them. Thus, the existence of human beings depend on them.
What is biodiversity Why is biodiversity important for human lives Brainly?
Answer: Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
What does biodiversity give to human lives?
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.
