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. SOIL
Soil is made up of a number of ________. Each having it’s own distinct ________ and _________.
The top layer is known as ______. It acts like a blanket limiting _____________ and reducing water loss.
Next is _______, made up of ______ mixed with decaying plant and animal matter called ______
Below topsoil is ________. It contains more _______ and some _______________.
The bottom layer is called _________. It is a solid rock.
layers
colour
texture
litter
temperature
topsoil
rocks
humus
subsoil
stones
Organic matter
bedrock

6. Soil can be _______, _______, or _________.
When it rains, _______ pulls the surface water into the ground through a process called ___________.
Eventually it reaches the __________, which is like and underground river. Plants _______ the water and it gets recycled back into the ____________.
Soil can be _______, _______, or _________.
The ____ determines which type of plants can grow in specific areas
gravity
percolation
water table
absorb
environment
acidic
basic
neutral pH

7. 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
