What are the 3 types of biodiversity and why are they important?
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.

- #1 – About one million plant and animal species face the threat of extinction1
- #2 – At least 680 vertebrate species have gone extinct since the 16th century1
- #3 – The majority of native species in land-based habitats have fallen by a minimum of 20% since the 1900s1
Why is biodiversity it important?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. 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 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 3 causes of decreased biodiversity?
Biodiversity loss is caused by five primary drivers: habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming.
How do you explain biodiversity to a child?
