  • Introduction to Ecology

    • What is an Ecosystem?

    • Stewardship and Sustainability

    • Biodiversity

    • Components of an Ecosystem

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


Terminology
Terminology

  • 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.
