1. Comparing Ecosystem
AQUATIC
TERRESTRIAL

2. Two Main Categories for Aquatic Ecosystems
Freshwater Ecosystems consist of moving bodies of water such as rivers and streams
These bodies of water are classified based
on their nutrient levels:
Oligotrophic:
A body of water that is LOW in nutrients
Eutrophic:
A body of water that is RICH in nutrients
Marine Ecosystems are mainly oceans (coral reefs) and make up more than 70% of the Earths surface.
Most of the water that evaporates in the air (water cycle)
is from the oceans

3. The main factor which determines a terrestrial ecosystem is…
CLIMATE
These regions are a collection of ecosystems that are similar or related and are called…
BIOMES
Canada is dominated by four main Biomes
TUNDRA
BOREAL
GRASSLAND
TEMPERATE DECIDUOUS FOREST

4. TEMPERATE DECIDUOUS FOREST
Comparison Chart
TUNDRA
Northern most Biome
Cold, desert
Poor soil quality
Supports a small # of species
Example: Caribou
BOREAL
South of the Tundra
Largest Biome (~80%)
Coniferous (needles)Trees
Much diversity
Found across every province
GRASSLAND
Next to deciduous
Many types of grasses
Some diversity
Rich fertile soil
Mice, snakes, hawks
TEMPERATE DECIDUOUS FOREST
Much diversity
Fertile soil
Deciduous (leaves) trees
Many Insects

5. Within both aquatic ecosystems and terrestrial ecosystems you have:
Artificial Ecosystems :
-An ecosystem planned and maintained by humans
Examples: parks, backyard, garden, farms etc…
Natural Ecosystems :
-An ecosystem not planned and maintained by humans, but
Not necessarily untouched
Examples: lake, river, forest etc…
Ecosystems naturally undergo change, they evolve through
A process called…
SUCCESSION
