BioDiversity. Lions and Tiger Lillies and Bacteria. What you should be able to do. Describe the diversity of species types on Earth, relating the difference between known numbers and estimated numbers List and describe 3 levels of biodiversity
Lions and Tiger Lillies and Bacteria
1.Biodiversity is connected to Ecosystem Health
Every species is either dependent on or depended upon by at least one other species. When one species disappears a strand in the food web is removed.
Species that are critical to the function of an ecosystem is a Keystone species. Ex. Loss of wolves led to explosion of deer population in Illinois
2.Genetic Variety increases the chances that species will survive environmental changes. When populations shrink, genetic diversity decreases.
3.Scientific community continues to find new uses for biological material for food, clothing and medicine
Ex. Clothing made from sustainable crops such as flax,
Taxol an anticancer drug derived from the North American Pacific Yew Tree.
Cultivation of new varieties of Corn-North America, Wheat-Africa, Rice-India
4. Value biodiversity because we enjoy green spaces and undisturbed land.
Ex. Ecoturism- a form of tourism that supports conservation and sustainable development of ecolologically unique area-Tours of the Grand Canyon
