My Ecological Footprint Assignment Outline
My Ecological
Footprint
Your
personal ecological footprint is how much land and resources it takes to maintain
your lifestyle. For example; how much area of the planet you need to produce
the resources you consume and to contain the waste you throw out. The less land
and resources you use, the better it is for ecosystems.
In this
activity, you will use an online ecological footprint calculator to determine
how much land and resources you are using to maintain your personal lifestyle.
The goal of this activity is to find ways to act more sustainably to help
reduce your ecological footprint. In other words; how can you change your
actions to help make ecosystems healthier?
Begin by
reading about ecological footprints by following the link below:
The Task
PART A
1. Follow
the link below to complete your ecological footprint
2. Select
“Calgary” from the virtual map; unfortunately “Toronto” cannot be selected
3. Select
“Kids Version”
4. Select
“Detailed Version”
5. Build
your “avatar” to represent you during the game
6. Answer
the questions in the quiz as accurately as possible
7. Read
through your results and print a copy
to submit with this assignment.
PART B
Write a ONE
PAGE response based on the results of your ecological footprint calculation. Your
response should answer the following question:
What actions can you take to help reduce your
ecological footprint and live in a more sustainable way?
Begin your
research by reviewing sections 3.2 and 3.3 (pages 68-81) in your Science
textbook.
The
following links may also help guide your response. Do not follow the “Take
Action” link on the results page of the ecological footprint; the link no
longer works.
Please
review the success criteria below to help you write your response.

Review crossword puzzles and worksheets for Chapter 2 in package
Review the following concepts:
- How matter cycles through an ecosystem and list abiotic elements that go through this cycle
- How much energy is passed along a food chain and why
- herbivores, carnivores, omnivores, scavengers, detritivores, decomposers, and all other roles in the ecosystem
- What is sustainability? How can we act in a sustainable way?
- How ecosystems change naturally over time
- How animals compete for resources
- Bioinvasion, introduced species and their effects on ecosystems (examples of these)
- How do limiting factors balance ecosystems?

Limiting Factors Notes
2.3
Interactions and Changes in Ecosystems
·
Limiting factors control or limit the number and
health of biotic elements in ecosystems
·
Examples
of limiting factors are the amount of food, water, energy, oxygen, and suitable
habitat available to organisms
·
Other
limiting factors can include; predators, hunting, or natural or human made disasters
·
Availability
of limiting factors can change in ecosystems; e.g., when higher rainfall
increases the number of producers and then the consumers have more food
·
Sometimes
changes can negatively impact availability of limiting factors; e.g., a forest
fire or bioinvasion
·
Bioinvasion is when a foreign species is introduced
into native ecosystems
·
A
native species occurs naturally in a
given area e.g., trout in Lake Ontario
·
An
introduced species is one that is
brought to an environment where it did not live before e.g., zebra mussels in
Lake Ontario
·
Introduced
species with no natural predators can quickly multiply and take over habitat
and deplete the food source of native species
·
Zebra mussels and Asian carp are known as invasive species
·
Competition – all living things in a community
compete for resources like food, water, and habitat; however, the supply of
these resources are limited
·
Living
things are always struggling to meet their basic needs at the expense of other
living things
