Biodiversity provides us with drinking water, oxygen to breathe, food, medicine, decomposition of waste, and helps our planet withstand natural disasters.
What are 3 direct services biodiversity provides to humans?
These services may be categorized as provisional, regulative, cultural or supporting services, also referred to as supporting processes (Table 1). The first three categories have a direct impact on human well-being, whereas the latter has an indirect impact by supporting provisional, regulative, and cultural services.
What are 3 services that ecosystems provide?
There, ecosystem services are grouped into four broad categories: provisioning, such as the production of food and water; regulating, such as the control of climate and disease; supporting, such as nutrient cycles and oxygen production; and cultural, such as spiritual and recreational benefits.
What are 3 types of 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. It occurs within a species as well as between species.
What are 3 ways biodiversity important?
Biodiversity provides vital ecosystem functions such as soil fertilization, nutrient recycling, pest and disease regulation, erosion control and crop and tree pollination.
What are the 3 main threats to biodiversity?
The three greatest proximate threats to biodiversity are habitat loss, overharvesting, and introduction of exotic species.
What are three types of diversity that contribute to a region’s overall biodiversity?
What are three types of diversity that contribute to a region’s overall biodiversity? Genetic diversity, species diversity, and ecosystem diversity.
What are biodiversity services?
Many key ecosystem services provided by biodiversity, such as nutrient cycling, carbon sequestration, pest regulation and pollination, sustain agricultural productivity. Promoting the healthy functioning of ecosystems ensures the resilience of agriculture as it intensifies to meet growing demands for food production.
What are the 4 types of biodiversity?
Four Types of Biodiversity
- Species Diversity. Every ecosystem contains a unique collection of species, all interacting with each other. …
- Genetic Diversity. Genetic diversity describes how closely related the members of one species are in a given ecosystem. …
- Ecosystem Diversity. …
- Functional Diversity.
What are the biodiversity ecological services?
Ecosystem services are the goods and services that biodiversity provides. They include soil formation, the provision of food and fibre, air quality and climate regulation, the regulation of water supply and quality and the cultural and aesthetic value of certain plants and species.
What are the 3 levels of biodiversity and why are they important?
Biodiversity occurs in three different levels: Genetic, Species, and Ecosystem. Genetic diversity refers to the differences within members of a species and their ability to adapt to changes. Species diversity refers to the total number of plant, animal, and insect species that can be found in a particular region.
What are the three levels of biodiversity with definition?
There are three levels of biodiversity:
- Genetic diversity: It refers to the variation in gene within a species. …
- Species diversity: It refers to the variety of species within a region.
- Ecosystem diversity: It include all the species and all abiotic factors characteristic of a region.
What are 3 causes of decreased biodiversity?

- Destruction of habitats.
- Invasive alien species.
- Overexploitation of the natural environment.
- Extinction of species.
- Threat to human beings.
