1. Biodiversity: Who cares?

2. Ecosystems ECOSYSTEM: All of the living and nonliving things that interact in a particular environment. Ecosystems can be as small as a meadow or swamp or as large as a desert or forest.

3. Species Organisms that are so similar that they can produce offspring that can also produce offspring. Organisms that are so similar that they can produce offspring that can also produce offspring. Ex: humans, dogs or cats are species Ex: humans, dogs or cats are species

4. Populations A group of organisms that are of the same species that live in a particular area. A group of organisms that are of the same species that live in a particular area. Ex: The people who live in Pittsburgh are a population. Ex: The people who live in Pittsburgh are a population. Ex. A population of cacti in the Mohave desert Ex. A population of cacti in the Mohave desert

5. Communities A group of populations that live in a particular area that interact with one another. A group of populations that live in a particular area that interact with one another. Ex: Cacti, iguanas, and crabs are part of the Galapagos Island Community Ex: Cacti, iguanas, and crabs are part of the Galapagos Island Community Ex. Gazelles, Lions and grasses are part of the African Savannah. Ex. Gazelles, Lions and grasses are part of the African Savannah.

15. What do you think biodiversity means?

16. Bio = Bio diversity What does “ Bio ” mean?

17. Diversity = Variety What does “ Diversity ” mean?

18. Biodiversity is the variety of life on Earth and the essential interdependence of all living things Scientists have identified more than 2 million species. Tens of millions -- remain unknown The tremendous variety of life on Earth is made possible by complex interactions among all living things including microscopic species like algae and mites.

19. There are 3 components of biodiversity 1. Diversity of genes Chihuahuas, beagles, and rottweilers are all dogs—but they're not the same because their genes are different. Chihuahua Beagle Rottweilers

20. Diversity of species For example, monkeys, dragonflies, and meadow beauties are all different species. Saki Monkey Golden SkimmerMeadow Beauty There are 3 components of biodiversity

21. Variety of ecosystems Prairies, Ponds, and tropical rain forests are all ecosystems. Each one is different, with its own set of species living in it. Paines Prairie Hoh Rain Forest Florida Sand hill Pond There are 3 components of biodiversity

32. Should we be concerned about biodiversity? What we know: The Earth is losing species at an alarming rate Some scientists estimate that as many as 3 species per hour are going extinct and 20,000 extinctions occur each year. Some scientists estimate that as many as 3 species per hour are going extinct and 20,000 extinctions occur each year. when species of plants and animals go extinct, many other species are affected. when species of plants and animals go extinct, many other species are affected.
