Topic outline
Ecosystem Components (LG 1-3)
BIG IDEA – Diversity of Ecosystems:
Complex roles and relationships contribute to diversity of ecosystems.
Content Learning Standards
Students are expected to know the following:
- abiotic
characteristics:
- aquatic (e.g. pH, flow, dissolved oxygen, turbidity,
salinity)
- atmospheric (e.g. sunlight, wind, temperature, pressure)
- edaphic - soils (e.g. pH, mineral content, water content, temperature,
acidity, aeration, nutrients, humus)
- topography (e.g. altitude, slope, exposure, mountain chains, valleys, plains) - levels of biotic diversity (e.g. ecosystem, species, genetic)
- interactions between biotic and abiotic

Ecosystem Behaviour (LG 4-6)
BIG IDEA – Diversity of Ecosystems:
Complex roles and relationships contribute to diversity of ecosystems.
Content Learning Standards
Students are expected to know the following:
- roles (e.g. niche, autotrophs, heterotrophs, producers, consumers, decomposers, scavengers, keystone species)
- energy flow through ecosystems (e.g. food chains, food webs, photosynthesis, respiration, trophic levels, productivity, pyramids of energy and biomass)
- relationships between organisms (e.g. predator/prey, competition, pollination, symbiosis, mutualism, parasitism, commensalism, mimicry)
Labels: 17URL: 1Ecosystem Processes (LG 7-9)
BIG IDEA – Changing Ecosystems:
Changing ecosystems are maintained by natural processes.
Content Learning Standards
Students are expected to know the following:
- matter cycles through and between living systems (e.g. water, nitrogen, carbon, phosphorus)
- population dynamics (e.g. cyclic fluctuations, birth rate, fertility rate, carrying capacity)
- ecosystem change (e.g. primary and secondary succession, introduced species, invasive species, )
Labels: 12- matter cycles through and between living systems (e.g. water, nitrogen, carbon, phosphorus)
Environmental Degradation (LG 10 - 12)
BIG IDEA – Sustainability of Ecosystems:
Human practices affect the sustainability of ecosystems.
Content Learning Standards
Students are expected to know the following:
- human actions and their impact on ecosystem integrity (e.g. harvesting, resource extraction and consumption, population growth, urbanization, habitat loss and fragmentation, climate change, pollution, forest fires)
Labels: 7Environmental Sustainability, Stewardship & Restoration (LG 13 - 15)
BIG IDEA – Sustainability of Ecosystems:
Human practices affect the sustainability of ecosystems.
Content Learning Standards
Students are expected to know the following:
- First Peoples knowledge and other traditional ecological knowledge in sustaining biodiversity
(e.g.agriculture, ethnobotany, forestry, fisheries, mining, energy, controlled burning, harvesting cycles) - benefits of ecosystem services
(e.g. water purification, pollination, climate regulation, medicines, food production, waste management) - First Peoples ways of knowing and doing (prescribed fire, selective harvesting, plant propagation and pruning, clam gardens)
- resource stewardship, the sustainable use of, and care for, local resources (e.g., school garden, shoreline cleanup, citizen science projects)
- restoration practices for renewing and recovering a degraded, damaged, or destroyed ecosystem (e.g. riparian zone recovery, invasive species removal, native species planting, ecological engineering, dam removal, hatcheries, wildlife, forestry and fisheries management)
Labels: 13- First Peoples knowledge and other traditional ecological knowledge in sustaining biodiversity
