success criteria
Success Criteria
  • By the end of this class I can
    • Compare and contrast abiotic and abiotic factors
    • Identify factors within an ecosystem that make it sustainable or unsustainable
case study unit big idea
Case Study & Unit Big Idea
  • Case Study Instructions
    • Read the article on “Cootes Paradise” p.g. 4-5
    • Have each person take a role:
      • What – is the issue?
      • Where – location, geography, details
      • When – events leading up issue
      • How – is the issue being solved?

Big Idea – How can we balance our need for resources and protect the environment?





what is an ecosystem
What is an Ecosystem?
  • A community of living organisms (plants, animals, & microbes) in conjunction with the non-living components of their environment (air, water, mineral, soil) interacting as a system.
  • Nutrient Cycles
  • Carbon Cycle
  • Nitrogen Cycle
  • Water Cycle
  • Energy Flows
  • Photosynthesis
  • Cellular Respiration
what is an ecosystem1
What is an Ecosystem?
  • Interaction between living and non-living factors
    • Abiotic = non-living
    • Biotic = living
  • Activity – Biotic vs. Abiotic
what is sustainability
What is Sustainability?
  • How would you explain the word sustainability?
what is sustainability1
What is Sustainability?
  • A sustainable environment has populations that can interact and reproduce indefinitely
    • Includes plants, animals and any other living things
  • It also means biodiversity is maintained
    • The number of different types of organisms in an area
what is stewardship
What is Stewardship?
  • A way of acting that takes into account personal responsibility for the management and care of something
    • Environmental stewardship is acting in a way that benefits the planet
    • This type of attitude is very common in First Nations communities
the environment
The Environment??
  • All the living and non-living things on earth and the interactions between them
  • The environment can be thought of as a system of components
    • Some interactions are positive: Bee pollinating a flower
    • Some are negative: Bee stinging you and dying
representing earth s biodiversity
Representing Earth’s Biodiversity
  • In groups of 3-4 complete the quick lab on p.g. 6 ‘Representing Earth’s Biodiversity’
what is a species
What is a Species?
  • A species is a group if similar organisms in an ecosystem which can reproduce and whose offspring can reproduce
    • i.e. grey squirrel species ≠ red squirrel species
    • Sciuruscarolinensis ≠ Sciurus vulgaris
  • Population: a group of individuals of the same species within a specific area
  • Habitat: the specific location a population lives in
  • Community: is made up of populations of different species that live and interact in an area or habitat
  • Species Niche: is the total of all the interactions of a given species within its ecosystem
ecology unit
Ecology Unit
  • Ecology is the study of how organisms interact with one another and the environment itself
ecosystems combine to form biomes
Ecosystems Combine to Form Biomes
  • Biome = a large geographical area that contains similar ecosystems.
biomes combine to make the biosphere
Biomes Combine to Make the Biosphere
  • Biosphere – is the part of the planet, including water, land, and air, where life exists.
ecosystem field study
Ecosystem Field Study
  • Complete an ecosystem field study in groups of 3-4 using the ecology tools provided by the teacher.
