Sustaining Earth’s Ecosystems Biomes
• ______________ is a term used to describe the _________
species and ecosystems on Earth and the
__________________ _________of which they are a part.
Biodiversity includes ____ living species of plants,
animals, and micro‐organisms on Earth.
Biodiversity is often referred to as ________________.
• Three components of biodiversity are
1. __________________
2. __________________
3. __________________
• Ecosystems perform functions that are _________ to human existence such as _________ and
_________ __________________ and ___________________________.
The Biosphere • The __________________ is a core concept within Biology and Ecology.
• The biosphere serves as the _________ level of biological organization which begins with parts of cells
and proceed to populations, species, eco‐regions, biomes and finally, the biosphere.
• __________________of biodiversity within the biosphere are __________________ using _________.
• The biosphere plays a _________ role in the biogeochemical processes:
i.e. __________________________________________
____________________________________.
Biomes • The biosphere consists of _________.
• Each biome contains many __________________.
• Each ecosystem contains __________________ in which a ________
__ ___________________________.
Biomes • A biome is a region with __________________and _________ components.
1. Biotic = __________________– plants, animals, fungi & micro‐
2. Abiotic = __________________g things (air, water, soil, etc.)
If biotic and abiotic conditions are the _________, similar biomes can exist _____ apart.
A biome here in B.C. can be the same as a biome in New Zealand.
Biomes are __________________ based on many qualities, such as
_____________________, __________________, and __________________ between biotic
and abiotic factors.
Examples of Biomes:
___________________________
__________________Forest
__________________Forest

Factors That Influence the Characteristics and Distribution of Biomes • Certain __________________ help __________________ biomes.
__________________ and __________________ are two of the most important abiotic factors.
Other factors include __________________, __________________, and __________________.
• Practice: Identify the biome using the
chart below.
Ave annual precipitation of
175cm and ave annual
temperature of 50C.
__________________
Temperature ranges 00C –
200C and receives about 100
cm of rain.
___________________________
• __________________ is an ___________________________that influences biomes.
Latitude is the ___________________________and _________ from the _________.
Latitude influences both __________________ and __________________.
The ___________________________has __________________temperatures and
_________ precipitation.
The tropical zone receives _________ direct sunlight than do temperate
zones.
• Elevation is the _________ of a land mass ___________________________and also influences biomes.
• Elevation effects __________________:
The atmosphere is _________ at higher elevations, and therefore __________________ ____.
• Elevation effects __________________:
On the __________________ sides of mountains, clouds filled with moisture
__________________ , then release ___________________________.
On the ___________ side of a mountain, which is the side ____________ from the wind, the
air warms again, which allows it to absorb water, creating a ___________________________.
• Ocean currents are another ___________________________ that affects __________________ and
___________________________ and therefore influences biome characteristics.
• Ocean currents _____________________________________________ to coastal areas.
Where warm currents meet land, temperate biomes are found.
e.i. Both Canada’s and New Zealand’s temperate rainforest.
• •
Climatographs • Climate refers to the ___________________________of ____________________________________
of a large region over a period of ___________________________. A ___________________________ shows the average temperature and precipitation for a
location over a period of 30 years or more. • Biomes are often defined using information in climatographs.
Examine the differences between the climatographs for Tofino and Osoyoos
Adaptations and Biomes • Biomes are often identified with ____________________________________.
• Certain types of plants and animals are characteristic of certain biomes because they are _________
__________________ for survival in the environmental conditions in those locations.
Such as a cactus in the desert or a caribou on the tundra.
An adaptation is a ______________________________________________________________
_____________________________________________.
3 types of Adaptations
1. ____________________________________– a __________________ that helps an organism
_________
A wolf has large paws to help it run in snow.
2. ____________________________________– a ___________________________________________
of an organism that allows it to _________
A wolf maintains a constant body temperature.
3. ____________________________________– a __________________ that helps an organism to
__________________
Wolves hunt in packs to capture large prey.
