27. Introducing Ecosystems species: individuals who can breed together to make fertile offspring

28. Introducing Ecosystems species: individuals who can breed together to make fertile offspring e.g. rabbitsnotmules

29. Introducing Ecosystems species: individuals who can breed together to make fertile offspring population: all the members of the same species that live in the same ecosystem

30. Introducing Ecosystems species: individuals who can breed together to make fertile offspring population: all the members of the same species that live in the same ecosystem e.g. a deer population

31. Introducing Ecosystems species: individuals who can breed together to make fertile offspring population: all the members of the same species that live in the same ecosystem community: all the living organisms, from all the populations, that live in the same ecosystem e.g. Beaver Pond community

32. Introducing Ecosystems e.g. Beaver Pond communitymembers

33. Introducing Ecosystems e.g. Beaver Pond communitymembers beavers ducks spruce trees deer maple trees frogs fish sparrows algae spiders mould amoeba

34. Biodiversity in Ecosystems Biodiversity: Variety of different species in an ecosystem. Rainforests have the highest biodiversity. Does our classroom have a high biodiversity?

35. The International Union for Conservation of Nature (IUCN) notes in a video that many species are threatened with extinction. In addition, At threat of extinction are 1 out of 8 birds 1 out of 4 mammals 1 out of 4 conifers 1 out of 3 amphibians 6 out of 7 marine turtles 75% of genetic diversity of agricultural crops has been lost 75% of the world’s fisheries are fully or over exploited Up to 70% of the world’s known species risk extinction if the global temperatures rise by more than 3.5°C 1/3rd of reef-building corals around the world are threatened with extinction Over 350 million people suffer from severe water scarcity
