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 Instructions
Read the article on “Cootes Paradise” p.g. 4-5

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
- Photosynthe
sis- Cellular
Respiration
What is an Ecosystem? Interaction
between living and non-living factors Abiotic = non-
living Biotic = living
Activity – Biotic vs. Abiotic
What is Sustainability?
How would you explain the word sustainability?
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? 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?? 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
When Self-Sustaining goes Wrong…
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? 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
Sciurus carolinensis ≠ Sciurus vulgaris
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 is the study of how organisms
interact with one another and the environment itself
Ecosystems Combine to Form Biomes
Biome = a large geographical area that contains similar ecosystems.
Biomes Combine to Make the Biosphere
Biosphere – is the part of the planet, including water, land, and air, where life exists.
Biomes Combine to Make the Biosphere
Ecosystem Field Study
Complete an ecosystem field study in groups of 3-4 using the ecology tools provided by the teacher.
