Introducing Ecosystems Introducing Ecosystems Ecosystem: all the living organisms in an area and their non-living environment Introducing Ecosystems Ecosystem: all the living organisms in an area and their non-living environment -components of an ecosystem are interrelated Introducing Ecosystems Ecosystem: all the living organisms in an area and their non-living environment -components of an ecosystem are interrelated -changes to one component can affect others Introducing Ecosystems Ecosystem: all the living organisms in an area and their non-living environment -components of an ecosystem are interrelated -changes to one component can affect others Biotic Factors: living things, their remains, and the features, such as nests, associated with their activities Introducing Ecosystems Ecosystem: all the living organisms in an area and their non-living environment -components of an ecosystem are interrelated -changes to one component can affect others Biotic Factors: living things, their remains, and the features, such as nests, associated with their activities Abiotic Factors: the non-living characteristics of an ecosystem Introducing Ecosystems Biotic or Abiotic? 1. moose Introducing Ecosystems Biotic or Abiotic? 1. moose -biotic Introducing Ecosystems Biotic or Abiotic? 1. moose -biotic 2. bird's nest Introducing Ecosystems Biotic or Abiotic? 1. moose -biotic 2. bird's nest -biotic Introducing Ecosystems Biotic or Abiotic? 1. moose -biotic 2. bird's nest -biotic 3. road kill Introducing Ecosystems Biotic or Abiotic? 1. moose -biotic 2. bird's nest -biotic 3. road kill -biotic Introducing Ecosystems Biotic or Abiotic? 1. moose -biotic 2. bird's nest -biotic 3. road kill -biotic 4. mushroom Introducing Ecosystems Biotic or Abiotic? 1. moose -biotic 2. bird's nest -biotic 3. road kill -biotic 4. mushroom -biotic Introducing Ecosystems Biotic or Abiotic? 1. moose -biotic 2. bird's nest -biotic 3. road kill -biotic 4. mushroom -biotic 5. cheese Introducing Ecosystems Biotic or Abiotic? 1. moose -biotic 2. bird's nest -biotic 3. road kill -biotic 4. mushroom -biotic 5. cheese -biotic Introducing Ecosystems Biotic or Abiotic? 1. boulder Introducing Ecosystems Biotic or Abiotic? 1. boulder -abiotic Introducing Ecosystems Biotic or Abiotic? 1. boulder -abiotic 2. rain Introducing Ecosystems Biotic or Abiotic? 1. boulder -abiotic 2. rain -abiotic Introducing Ecosystems Biotic or Abiotic? 1. boulder -abiotic 2. rain -abiotic 3. lightning Introducing Ecosystems Biotic or Abiotic? 1. boulder -abiotic 2. rain -abiotic 3. lightning -abiotic Introducing Ecosystems Biotic or Abiotic? 1. boulder -abiotic 2. rain -abiotic 3. lightning -abiotic 4. carbon dioxide Introducing Ecosystems Biotic or Abiotic? 1. boulder -abiotic 2. rain -abiotic 3. lightning -abiotic 4. carbon dioxide -abiotic Introducing Ecosystems Biotic or Abiotic? 1. boulder -abiotic 2. rain -abiotic 3. lightning -abiotic 4. carbon dioxide 5. the thing -abiotic Introducing Ecosystems Biotic or Abiotic? 1. boulder -abiotic 2. rain -abiotic 3. lightning -abiotic 4. carbon dioxide 5. the thing -abiotic no idea????? Introducing Ecosystems species: individuals who can breed together to make fertile offspring Introducing Ecosystems species: individuals who can breed together to make fertile offspring e.g. rabbits not mules 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 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 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 Introducing Ecosystems e.g. Beaver Pond community members Introducing Ecosystems e.g. Beaver Pond community members beavers ducks spruce trees deer maple trees frogs fish sparrows algae spiders mould amoeba Biodiversity in Ecosystems • Biodiversity: Variety of different species in an ecosystem. • Rainforests have the highest biodiversity. • Does our classroom have a high biodiversity? • • • • • • • • • • • • 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
