2. Two different names for Tropical Savanna
1.tropical grassland
2.rolling grassland

3. Location and
climate
Located between Tropic of Cancer and the Tropic of
Capricorn. Covers large areas of Australia, South America,
and India. Temperature: 78 degrees to 80 degrees
Fahrenheit. Wet season-summer warmer in the rainy season
than the dry season because it is humid. Annual Rainfall:
Between 30-50 inches (4 inches a month, during dry season)

5. Characteristics of plants and animals
•Animals:
Wildebeest Zebras Rhinos Termites
Giraffes Jackals Hyenas

6. Characteristics of plants and animals
•Plants:
Elephant grass Rhodes grass Baobab tree

7. Energy Flow
The food pyramid shows how energy flows through the food chain
and the feeding relationships of groups of organisms.

8. Energy Flow
To the left is the biomass pyramid
and to the right is the number
pyramid. Both represent the energy
flow is the biome. It is demonstrated
how the energy flows from
producers to secondary consumers
and loses energy in the process of the
transfers.

9. The food chain represents how
one chain of animals receives
its energy from its diet. The
food web shows how different
chains can work in the biome.
A hyena can eat a zebra or a
cheetah can eat a zebra. Both
secondary consumers receive
the same amount of energy
from the primary consumer.

10. Primary Productivity
vTropical Savannas have
fairly high levels of net
primary productivity. It
makes 3000 Net Primary
Productivity
(Kilocalories/square
meter/year).
vThe savanna gross primary
production is about 50
billion kcal/year.
vThe most advantageous
temperature at which
photosynthesis takes place
is from near freezing to 70
to 80°F. The rates of
photosynthesis and
respiration increase with
higher temperatures. Any
temperatures above or
below these levels limit
plant growth. The average
temperature of a tropical
savanna is around 75-80°F.

11. Succession
Primary succession
Primary succession is when something
grows in place where there was no growth
before. An example of primary succession is
if there is a volcanic eruption, moss grows on
the volcanic rock, short grass starts to form
from the soil formed from rock, the soil gets
deeper and the grass starts to get taller,
eventually when a big enough layer of soil
forms trees start growing.
Secondary Succession
Secondary succession is most common out
of the two, especially because of how
common seasonal fires are in this biome. The
seasonal fires burn down many trees,
grasses, and shrubs. Burnt plants clears from
the area and leaves the area with rich soil for
more to grow.

12. Human impact
MDC:
•Nigeria: in this region, land degradation is mainly caused by agricultural activities such as tree
felling fuel wood and timber production, crop expansion, and agricultural intensification. Due to
this, this region suffers from loss of soil fertility. What's being done to solve this is that
organizations, such as SHED-Africa, are working with rural and urban poor communities to raise
awareness. Another way is regulations that the Federal Government of Nigeria set fourth to regulate
forest activities.
•USA: In the US, longleaf pine savannas have been affected by logging. Due to this, it faces less
biodiversity since many species line in, on or near the trees being torn down; climate change and
decline in soil fertility. This is being solved by organizations raising awareness and separate tree
farms to provide timber.

13. Human impact
LDC:
•Somalia: this region suffers economically from loss of bio diversity due
to the hunting of animals so surrounding villages that don't have much
resources could eat these animals in order to live. This areas is solving
by having protected regions and finding other alternatives for resources
to use besides timber
•Ethiopia: due to how much the villages around this area use fire, the
spread of fire has destroyed the soil causing it to dry up and the use of
fire for hunting kills off many animals that destroys the bio diversity.
This is being solved by controlling intentional fires for hunting.

14. Differences
. The difference between MDC and LDC is how it is
handled. In an MDC, there are efforts to lessen the
destruction of the biosphere and these problems
can be solved simply by resorting to other ways to
both getting resources and not harming
ecosystems that are vital to plants and animals
but, with LDC not much is being done due to the
need to first survive rather than protect these
savannas so this isn't a top priority at this point.
Ways that people are trying to solve these
problems: Now many countries that have
savannas are regulating fires, hunting and logging
that destroys this environment. New laws are
being passed to prohibit activities that are
potential harmful to the environment.
