8. BIOMEBIOMEIs a distinct ecological community
of plants and animals living together
in a particular climate.
9. Biomes are climatically
and geographically defined as
contiguous areas with similar
climatic conditions on the
Earth, such as communities of
plants, animals, and soil
organisms, and are often
referred to as ecosystems.
11. Scientists have
divided the broad
spectrum of climates
and ecological
communities found
on Earth into biomes
in different ways -
some with many
divisions, some with
only a few.
15. Coniferous Forest
-are those consisting
mainly of spruce, pine,
fir and other evergreens
– directly and indirectly
provide nourishment and
shelter to plants, animals
and organisms in their
environment.
16. Three Subdivisions:
a. The TAIGA (tie- guh) is the northern
most area, in which the dominant is the
spruce is adapted to a six month growing
season and cold winter temperature.
b. The broad coniferous belt covers much
Canada, and in the United States, it extends
to the Great Laos area and the St. Lawrence
River Valley. The dominant vegetation is
white pine, red pine, and cavern hemlock.
Taiga in Russia is the largest forest in the world.
It accounts for one fifth of the total forested area in the world.
17. Three Subdivisions:
c. The natural pine forest is found in
much of the southern United States.
Coniferous forest has full time
residents. Moose lives in this area
where they are protected or where
they have not been overhunted.
Taiga in Russia is the largest forest in the world.
It accounts for one fifth of the total forested area in the world.
23. CHARACTERISTICS OF TUNDRA:
Long cold winters and short
cool summers
Low precipitation (less
than 10 inches per year)
and dry winds
Permafrost - ground that is
permanently frozen
Permafrost
Has no cracks or pores,
nothing can penetrate it--neither
plant roots nor water.
26. Is primarily composed of
trees with leaves-leaves that
die, fall off and regrow during
seasonal growing cycles.
Deciduous Forest
Deciduous Forest are
commonly found in:
United States
Great Britain
Central Europe
Some parts of China
Siberia
Rainfall averages about 100cm (40 inches) per year
27. Variety of different deciduous
climax vegetation:
a.Local condition of soil
b.Drainage
c.Climate
30. Serengeti Plain
Grasslandsare often
found in areas where yearly
rainfall is between 25 and 75
centimetre (10 to 30 inches).
Grasslands are sufficient for
many species of grasses.
African Savannah
31.
32. Tropical grassland of Africa is found in the
Serengeti Plain. The Serengeti is known as
“a variety of animal population”.
Savannah is a grassland with scattered trees.
34. Tropical Rainforest
- areas that have an
abundant water supply
a long growing season.
- have a rate of
productivity because of
the abundant resources
and favourable physical
factors. Animal’s life is plentiful in a tropical rainforest.
35. Tropical Rainforest
- A rainforest is not a jungle. A
jungle is a very dense ground
growth found along riverbanks.
Animal’s life is plentiful in a
tropical rainforest.
44. WILDLIFE
CONSERVATION
A.Includes all of man’s
efforts to save wild
animals.
B.It involves the protection
and wise management of
such animals and their
environment.
C.Although some species of
animals may have been
killed off by natural
causes, man is by far the
greatest danger to wildlife.
He has created the need
for wildlife conservation.
45. The threatened species
and all other wildlife - have
FOUR VALUES FOR MAN
includes:
a.Beauty
b.Economic value
c.Scientific value
d.Survival value
